Title:
boot luks splash kernel 6.8.0-5x

Status in linux package in Ubuntu:
Confirmed

Bug description:

bugs@lists.ubuntu.com/msg6121735.html


I can confirm the same behavior with Kubuntu 24.04 upgraded from
6.8.0-49 to 6.8.0-50. System boots to LUKS password prompt and I get 2
seconds or so to type before the screen blanks for 2 seconds. When it
returns I am unable to type. Using Grub Advanced I can force the boot
to 6.8.0-49 and everything works fine as before. Alternatively I can
use Grub Advanced to edit the 6.8.0-50 command line and remove quiet and
splash to do a text boot. In that mode I still get the flash behavior;
however, I am able to continue typing after the flash. I found several
Mint related posts complaining about the same kernel with the same
issue.

I habe the same problem on Ubuntu 24.04 since kernel 6.8.0-50 and
Ubuntu 24.10 after migration.


My system is an AMD 5950X with and AMD Radeon™ RX 7700 XT
