hello, after running the new kernel for a awhile, the system gives an error and switches from gui to a tty like in a kernel panic. if i use ctrl+alt+f7 i can get back to the gui. here is the latest incarnation of the error from /var/log/syslog, i got it 3 times so far, just letting you know.

Thanks for reporting, I'll see if I can get the UKSM authors to look at this trace. In the meantime, I'll push an update with UKSM enabled so no one else runs into this.

This is the "future" branch, so I'm in no particular hurry to update it. You may want to track "main" if you need your system to be reliable until then.

there is no problem for me. i just wanted to help you if possible. i assume the "risks" when i run the unstable and future repos. and this is my main rig, i don't need reliability on it. that sounded very hilarious, but you get the point. thanks.

edit: using 3.5.3-3 from day of release to current date, no more error. thanks.
