The previous kernel 6.17.0-14-generic boots without any issues.
I'll try to attach the required information using `apport-collect -p linux BUG#`, but it'll be collected after successfully booting with 6.17.0-14, whereas the bug occurs with 6.17.0-19.

linux-image-7.0.0-7-generic: dracut fails to include zfs module on
ZFS-on-root system (Ubuntu 26.04 Resolute)
Status in linux package in Ubuntu:
Confirmed
Bug description:
Bug Report: Kernel 7.0.0-7-generic unbootable on ZFS-on-root
Package: linux-image-7.0.0-7-generic (Version 7.0.0-7.7) / dracut
Severity: Critical (System unbootable)
Description:
During a routine upgrade on Ubuntu 26.04 Resolute Raccoon, the installation of kernel 7.0.0-7-generic fails to generate a valid initramfs using dracut. The process terminates because the zfs module cannot be found in the new kernel's directory, despite the system running on a ZFS root pool.
The resulting /boot/initrd.img-7.0.0-7-generic lacks the necessary
drivers to mount the encrypted ZFS root filesystem, leading to a
Kernel Panic or an emergency initramfs prompt upon boot.
Steps to Reproduce:
Use Ubuntu 26.04 (Resolute) installed on a ZFS root partition
(rpool).
Run sudo apt update && sudo apt upgrade.
Observe the dracut post-installation triggers for linux-
image-7.0.0-7-generic.
Actual Results:
dracut fails with the following error:
/etc/kernel/postinst.d/dracut:
dracut: Generating /boot/initrd.img-7.0.0-7-generic

Title:
linux-image-7.0.0-7-generic: dracut fails to include zfs module on
ZFS-on-root system (Ubuntu 26.04 Resolute)
Status in linux package in Ubuntu:
Confirmed
Bug description:
Bug Report: Kernel 7.0.0-7-generic unbootable on ZFS-on-root
Package: linux-image-7.0.0-7-generic (Version 7.0.0-7.7) / dracut
Severity: Critical (System unbootable)
Description:
During a routine upgrade on Ubuntu 26.04 Resolute Raccoon, the installation of kernel 7.0.0-7-generic fails to generate a valid initramfs using dracut. The process terminates because the zfs module cannot be found in the new kernel's directory, despite the system running on a ZFS root pool.
The resulting /boot/initrd.img-7.0.0-7-generic lacks the necessary
drivers to mount the encrypted ZFS root filesystem, leading to a
Kernel Panic or an emergency initramfs prompt upon boot.
Steps to Reproduce:
Use Ubuntu 26.04 (Resolute) installed on a ZFS root partition
(rpool).
Run sudo apt update && sudo apt upgrade.
Observe the dracut post-installation triggers for linux-
image-7.0.0-7-generic.
Actual Results:
dracut fails with the following error:
/etc/kernel/postinst.d/dracut:
dracut: Generating /boot/initrd.img-7.0.0-7-generic
dracut-install: Failed to find module 'zfs'
dracut[E]: FAILED: /usr/lib/dracut/dracut-install -D /var/tmp/dracut.XXXXXX/initramfs --kerneldir /usr/lib/modules/7.0.0-7-generic -m zfs

Regression: Kubuntu 26.04 with kernel 7.0.0-7-generic hangs at resume
from suspend with flickering screen
Status in linux package in Ubuntu:
New
Bug description:
Since the kernel upgrade to 7.0.0-7-generic, my test installation of Kubuntu 26.04 hangs with a flickering screen when I resume my PC from suspend-to-RAM.
This is a regression from linux 6.19.0-9-generic.
STEPS TO REPRODUCE
1. Boot Kubuntu 26.04 with kernel 7.0.0-7-generic, login to KDE Plasma Desktop.
2. Suspend-to-RAM.
3. Power on again.
ACTUAL RESULT
PC hangs with flickering screen (sample video attached below). Key presses, like for opening a TTY or Ctrl+Alt+Delete, do nothing. Only exception: SysRq+B for rebooting the machine still works.
EXPECTED RESULT
Suspend works :)
ADDITIONAL INFORMATION
If I boot the older kernel 6.19.0-9-generic, suspend works just fine, so it seems like a regression in 7.0.0-7-generic.
I have disabled the KDE screen locker.

If I boot the older kernel 6.19.0-9-generic, suspend works just fine, so it seems like a regression in 7.0.0-7-generic.
I have disabled the KDE screen locker.

Title:
Regression: Kubuntu 26.04 with kernel 7.0.0-7-generic hangs at resume
from suspend with flickering screen
Status in linux package in Ubuntu:
New
Bug description:
Since the kernel upgrade to 7.0.0-7-generic, my test installation of Kubuntu 26.04 hangs with a flickering screen when I resume my PC from suspend-to-RAM.
This is a regression from linux 6.19.0-9-generic.
STEPS TO REPRODUCE
1. Boot Kubuntu 26.04 with kernel 7.0.0-7-generic, login to KDE Plasma Desktop.
2. Suspend-to-RAM.
3. Power on again.
ACTUAL RESULT
PC hangs with flickering screen (sample video attached below). Key presses, like for opening a TTY or Ctrl+Alt+Delete, do nothing. Only exception: SysRq+B for rebooting the machine still works.
EXPECTED RESULT
Suspend works :)

[Bug 2054810] Re: Adding bpf to CONFIG_LSM in linux kernel
Hello, adding some context here as to why LSM hooks are important. LSM
hooks are used by different runtime security tools like Tetragon
(https://tetragon.io/docs/concepts/tracing-policy/hooks/#lsm-bpf) and
Tracee (https://aquasecurity.github.io/tracee/dev/docs/install/lsm-
support/). This was mainly driven by publications of techniques that
allowed bypassing those tools. The most recent publication is using
io_uring. https://www.armosec.io/blog/io_uring-rootkit-bypasses-linux-
security/ and a previous publication showed TOCTOU races are capable of
bypassing system call tracing like kprobes
(https://i.blackhat.com/USA-22/Wednesday/US-22-Guo-Trace-me-if-you-
can.pdf).
Thus, LSM hooks allow for robust runtime security monitoring. Enabling
this by default on Ubuntu allows such hooks to be adapted and leveraged
more widely in security tooling. And as per @esheri3's message (#2), to
be used in 3rd-party-operated infrastructure.
If there is anything that needs to be done, I'd be happy to support that
effort.

Bug description:
[ Impact ]
Due to a false negative result of runtime bounds checking, a kernel
panic occurrs on reception of erspan packet.
A bug has been discovered in the kernel networking code for handling
of erspan packets. It manifests itself when FORTIFY_SOURCE is enabled
and GCC 15.2+ compiler is used, both of which are true for Ubuntu
Questing and onwards.
[ Testc Plan ]
The Open vSwitch system test suite triggers the panic, and
consequentliy it can be used to confirm the fix.
[ Where problems could occur ]
The false negative occurs due to incorrect order of referencing
counter and the data protected by it, the fix is trivial and has been
merged both to mainline and stable for some time.
Probability of it causing undesired effects is minimal.
[ Other info ]
Steps to reproduce the issue:
1. sudo apt build-dep openvswitch
2. git clone https://github.com/openvswitch/ovs.git
3. cd ovs
4. ./boot.sh && ./configure && make -j$(nproc)
5. sudo make check-kernel TESTSUITEFLAGS="-j1 18"

Bug description:
[ Impact ]
Due to a false negative result of runtime bounds checking, a kernel
panic occurrs on reception of erspan packet.
A bug has been discovered in the kernel networking code for handling
of erspan packets. It manifests itself when FORTIFY_SOURCE is enabled
and GCC 15.2+ compiler is used, both of which are true for Ubuntu
Questing and onwards.
[ Testc Plan ]
The Open vSwitch system test suite triggers the panic, and
consequentliy it can be used to confirm the fix.
[ Where problems could occur ]
The false negative occurs due to incorrect order of referencing
counter and the data protected by it, the fix is trivial and has been
merged both to mainline and stable for some time.
Probability of it causing undesired effects is minimal.
[ Other info ]
Steps to reproduce the issue:
1. sudo apt build-dep openvswitch
2. git clone https://github.com/openvswitch/ovs.git
3. cd ovs
4. ./boot.sh && ./configure && make -j$(nproc)
5. sudo make check-kernel TESTSUITEFLAGS="-j1 18"

This isn't particularly suitable for projects that previously used
libcpufreq and intend to migrate to libcpupower, because the
libcpupower.so symlink is no longer installed. The command-line tools
can also have symlinks (e.g. cpupower -> cpupower_$(abi_version)).

New Dell Slate-1-Piece and Congo platform powered by Intel WildcatLake will have no basic audio functions w/o new firmware-sof which has the new DSP firmware and TPLG files

<=============== firmware-sof ========================
[Fix]
c78aea2df366275fed6c7b090bae3575951de57f Add 2.14.1 signed firmware binaries for Intel MTL+ targets

cdd3c8f9dd879a51dc8ed3c9aa0b7b0a49c108d8 Add 2.14 tools and topology binaries for Intel MTL and newer targets
11fc822288122b83296e634e8508f483c289d565 v2.14.x: add topologies for v2.14.2
e65a0d4f3ffceaf8a01df7f519707ffaf69746ef v2.14.x: add topologies for v2.14.3
[Test Case]
1. Boot up the machine of new Dell Intel WCL Congo and Slate-1-Piece platform powered by Intel WCL
2. Open settings->Sound->Output Device and make sure it's not Dummy audio devices
3. Click test icon for basic audio output functions
4. Use `arecord` to record and play the recorded audio file with `aplay` for basic speaker/microphone functions.
5. Test on machines of Intel ARL/LNL/MTL/PTL platforms for possible regression
[Where problems could occur]
Per comment from Intel, the primary requirement is that the topology file (sof-ptl-foo.tplg) and DSP firmware (sof-ptl.ri) are a pair and need to be from the same major version.
If we upgrade of FW for only a single generation (e.g. only for WCL)
This will be problematic. The main problem is that you may have two platforms (let's say
PTL and ARL) using same topology files. If you update FW for only PTL, you should also update the topology
files used by PTL (FW+tplg always a pair!), but then if one of the topology files is used by some ARL
products you may have problems (-> scenario 2 problem on ARL then).
So we need to upgrade the DSP FW and the TPLG both for all MTL+
platforms (include ARL/LNL/MTL/PTL/WCL)
