Today I updated several TW machines to 20241119 ( 2 physical machines and 3 vms ). All the updates when fine. When I rebooted one of the physical machines after selecting the grub entry to boot, the cursor in the left corner of a blank screen with no messages and roughly 30 seconds later the login GUI is displayed. Looking at the journal I found that plymouth is terminating with a segfault. It does not happen all the time but it does happen most times. If I do a shutdown/poweroff and then poweron sometimes it doesn't happen. If I do a reboot, then it seems to happen ever time. Is this a known issue ?
