Hi,
After install new kernel 6.11.8-300.fc41.x86_64 , when I start Fedora 41 KDE Plasma, enter passphrase to decrypt disk and login to Plasma, after few second my system is crashing - is just shut down entire laptop without any reason/error, sometimes is some freeze, but this is only on 6.11.8, when I back to 6.11.7 everything is back.
Furthermore, I see a some stuff doesn’t work - one of many is brightness screen.
Posting your syslog is going to be required - there’s no way anyone can assist without something to look at.
For syslog read system journal.
You can use the journalctl -b -1 to see the failed boots logs.
Ah - IBM MVS user so syslog trips off the toungue for me.
Just to avoid wasting your time: you can try if the issue/bug is already solved in 6.11.9:
sudo dnf upgrade --enablerepo=updates-testing --refresh --advisory=FEDORA-2024-c5baa66128
This command will install the 6.11.9 kernel, which is currently in testing, but the command will only get the kernel and its packages from testing for one time. This command will NOT enable testing by default or so.
6.11.9 has been already tested by many people without issues:
https://bodhi.fedoraproject.org/updates/FEDORA-2024-c5baa66128
→ therefore, it is likely that it is pushed to stable quickly anyway.
Maybe that already solves the issue 
Otherwise, if 6.11.9 does not help, it might be useful to get the journal, as Barry already suggested. But beyond the whole log, it might be useful to also have a log that contains only kernel messages (add option -k to Barry’s command). If you prefer providing rather less than more details, you might start with the kernel logs only. Given what you elaborate, I assume the kernel entries are the major indicators anyway. But let’s hope that 6.11.9 solves the issue
