[Bug 2147294] Re: Regression: Ubuntu 24.04 HWE kernel 6.17 causes multiple device/input failures after reboot

This indicates the 6.17 kernel did not install/configure correctly. Usually, it is caused by either:
1. An external kernel module not building. Check output of:
sudo dkms status

2. bug 2115148

If you cannot figure it out, run the following command and copy/paste output:
sudo apt dist-upgrade

** Package changed: linux (Ubuntu) => linux-hwe-6.17 (Ubuntu)

** Changed in: linux-hwe-6.17 (Ubuntu)
Status: New => Incomplete

Title:
Regression: Ubuntu 24.04 HWE kernel 6.17 causes multiple device/input
failures after reboot

Status in linux-hwe-6.17 package in Ubuntu:
Incomplete

Bug description:
After updating Ubuntu 24.04 LTS to a recent HWE 6.17 kernel, the
system developed a serious regression after reboot.

What I expected to happen:
The system should boot normally, with working input devices and peripherals, as before the update.

What happened instead:
After reboot, the system became partially unusable. At minimum, the internal keyboard stopped working. Other peripherals also appeared to be affected, including the microphone. The mouse still worked, and the display was visible, but I could not fully determine the exact extent of the breakage from the broken graphical session alone.

Why I am reporting this generically:
I cannot confidently identify every subsystem that failed. The issue looked broader than a single device failure, so I am reporting it as a kernel regression affecting peripherals / input / general usability rather than only one specific component.

Regression:
Yes. The problem appeared after updating to the HWE 6.17 kernel series, and the system recovered after removing the problematic 6.17 kernels and going back to the stable generic kernel.

Recovery / workaround:
I recovered the machine from an Ubuntu Live USB. I mounted the installed system, entered it through chroot, removed the problematic 6.17 kernel packages, reinstalled the stable generic kernel, regenerated initramfs, and updated GRUB. After reboot, the system started correctly again on 6.8.0-107-generic.
