I often have random freezes in X11. It happened with 11.2-RELEASE, I upgraded to 12.0-CURRENT, it still happens. From /var/log/Xorg.0.log: (EE) (EE) [mi] EQ overflow continuing. 1000 events have been dropped. (EE) [mi] No further overflow reports will be reported until the clog is cleared.

(?+0x94) [0x800498094] I'm using Geforce GTX650Ti with x11/nvidia-driver.
It only happens with Nvidia GPU, it doesn't happen with Radeon or Intel on other computers.
Did you boot via UEFI or legacy BIOS/CSM? Can you post Xorg.log? It's not clear what is at play. For one, sysmouse tends to be more buggy than using ums directly. (In reply to Piotr Kubaj from comment #1) On otherwise the same hardware? Have you tried downgrading nvidia-driver to previous version?
(In reply to Jan Beich from comment #2) It uses BIOS/CSM. I could paste my Xorg.log, but it was overwritten, so next time it happens, I will put it here. Radeon and Intel cards work, but on other hw, I didn't test other cards on this PC. I'm not sure how long it was since it started, it actually belongs to my parents...
(In reply to Piotr Kubaj from comment #3) BTW, I can SSH in just fine and even restart X11, so if you wish, I can do some live debugging next time it happens (just need to know what to check).
Created attachment 198209 [details] Xorg.0.log It happened again. Here's my log.
Does the problem still exists?
(In reply to Walter Schwarzenfeld from comment #6) Yes.
Reminds me of https://forums.freebsd.org/threads/eq-overflow-freebsd-12-0-nvidia-1660ti-with-430-driver-ryzen-2400g.71281/.
It turns out the issue was caused by KDE. I'm not sure why and I can't investigate it because the PC is a couple hundred kilometers away and used by my parents. It seems stable with XFCE though (or anything else). It's not Xorg's or Nvidia's issue because the problem was still happening after replacing with Radeon.
