>From my side I can add that it was not a full system freeze, but inability to enter characters from keyboard (from both laptop one, and an external keyboard attached via USB).
Even though CapsLock LED was reacting on keypress and Ctrl+Alt+Del restarted the system. Also I managed to do the following: 1. Waited for the very initial load of GUI with password input 2. During first 1-2 seconds I managed to type 4-5 characters - and clearly saw them represented in the input field (so in fact I saw 4-5 circles there aka "masked input") 3. Then the screen blinked once and after that I was still able to see an old input, but had no chance to enter more characters. My system details back then were the following: OS: Ubuntu 24.04 noble Kernel: x86_64 Linux 6.8.0-50-generic GPU: AMD Radeon Graphics (radeonsi, rembrandt, LLVM 17.0.6, DRM 3.57, 6.8.0-50-generic) Now I downgraded the kernel to 6.8.0-49-generic and the problem disappeared. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/2091753 Title: Plymouth fails with kernel 6.8.0-50 Status in linux package in Ubuntu: Confirmed Bug description: Plymouth fails to fully boot with this kernel when asking for encryption password for local partition. The system freezes and can be recovered in rescue mode. Previous kernels accepted the password and continued to X as expected. Remove 'splash' from GRUB_CMDLINE_LINUX_DEFAULT="quiet" prevents plymouth from loading and booting continues to X after password is entered in when booting pauses and asks for the password in the terminal. This behaviour is true on laptops running Linux Mint (Wilma) and Ubuntu KDE 24.04 with encrypted partitions. On devices without encrypted partitions 'quiet splash' is included on the kernel command line and booting proceeds as expected.
