[Bug 1973167] Re: linux-image-4.15.0-177-generic freezes on the welcome screen

We are waiting for the new kernel too as we are currently blocked with
new installations based on 18.04 LTS. Can you please give a date when it
will be ready? Thanks!

Title:
linux-image-4.15.0-177-generic freezes on the welcome screen

Status in linux package in Ubuntu:
Confirmed
Status in linux source package in Bionic:
Confirmed

Bug description:
After updating to linux-image-4.15.0-177-generic, my machine
completely freezes on the Ubuntu Welcome screen, i.e. right after
switching to GUI mode. The mouse pointer is frozen, the keyboard does
not even respond to CAPS LOCK or NUM LOCK, pressing CTRL+ALT+F2 shows
no reaction.

I cannot work with my machine at this point and have to hard reset it.

Selecting advanced boot options in grub and selecting the previous
linux kernel 4.15.0-176 makes it work again. So this bad bug was
introduced with the 4.15.0-177 kernel release.

I tried removing the nvidia-driver-510 package, presumably making
Ubuntu use the "nouveau" driver, and with that, I could use the
welcome screen and log in, but the machine still froze shortly
afterwards.

So maybe this is some sort of interference with my GeForce 1080
graphics card, but it is not specific to the driver used.
