Title:
unable to boot kernel 5.15.0.50
Status in linux package in Ubuntu:
Confirmed
Bug description:
Hi,
After a fresh install of Ubuntu 22.04 I'm unable to boot with kernel
5.15.0.50
Normal boot on 5.15.0.50 : stuck at boot with the following message :
INFO: task gpu-manager:749 blocked for more than XXX seconds
I deactivated the silent splash screen on Grub to get more details
about what's wrong :
"a start job is running for Detect the available GPU..."
Recovery mode on 5.15.0.50: I can boot but after login only integrated
monitor is working
Normal boot on 5.15.0.43: No issue
Configuration: Alienware 15R3 Nvidia GTX 1080 Mobile + Integrated
Intel GPU
Nvidia drivers: 515
What I'v done so far :
-Deactivated gpu-manager in grub: no effect
-Uninstall intel-microcode or downgraded intel-microcode : no effect
-Tried various nvidia drivers: no effect
-Tried other external monitors: no effect
