After the latest updates in Slackware64 --curent (the latest kernel change), my system became a bit unstable. Occasionally, while browsing in Firefox, I first hear the fan start spinning fast and then everything freezes. I can't even check what process is involved, because the keyboard is frozen too.

I tried with opening top and setting it above all windows before the problem happens, but nothing unusual was detected. It usually happens when I'm working in my google docs, once happened while I was reading and scrolling the Twitter. I suspected ,but not sure, that it has something to do with the nvidia kernel module. Did anyone face similar issues? Any thoughts? Thanks!

edit: I use default system settings

Using nouveau or the proprietary NVidia driver?

It's nouveau, I don't remember the last time I used proprietary, probably several years ago. Maybe I should give it a try. Of course, if this is really a driver problem, I don't know that, just guessing.

Can’t say if it’s the same issue, but something similar did happened to me twice in a few hours today. I was running the newest 5.10.2 kernel since the day before (compiled by myself, not the one provided by -current) on a version of -current frozen in June 2020.

I switched back to my previous 5.4.79 kernel and have not experienced the issue again, so I am inclined to blame the 5.10.x kernel. It cannot have anything to do with Nouveau, though, because I’m using a Intel GPU (driver i915).

This system uses both i915 and NVIDIA, and I guess the freeze happens when I do something that requires switch to the latter one. I've just installed proprietary NVIDIA drivers, so we'll see. Thanks!

Unfortunately, switching to the proprietary driver didn't help. I hope the next kernel upgrade will fix this issue.

Getting that particular hardware working properly in Linux can be a "non-trivial" task, depending upon the specifics.

I've not attempted it myself, but you can read about it here: https://docs.slackware.com/howtos:ha...nvidia_optimus

I've noticed some module name changes recently in the 5.10.x series. They impacted my initrd process and may be impacting others differently.

I have been having this issue for 6days now, both on a laptop and a desktop, and there seems to be no solution. Correction: I believe that only thing that could work will be switching back to previous kernel version (just before 21st of Dec). I am not sure how to this and whether i will risk causing a total crash on my desktop which will cost me 8mnths of settings and work.

it is definitely the video driver; i had the same problem 2yrs ago and it resolved by manually installing the proprietary nvidia driver. This time for some GCC-version reason nvidia driver cannot build correctly on the kernel 5.10.2 so, i am also stuck with a glitching screen and forced to disconnect the second monitor to avoid more frequent system crashes (you can read the thread i started 6days ago here).

I really do not know what else to try so, I hope that the slackware developers will give us a New Year present by fixing this in the next kernel patch.

p.s.: if you come up to something that works, please share

For the build of the nvidia driver with gcc 10, there is :
./nvidia-installer -K --no-unified-memory

5.10.y has proved unreliable for me also.

I know 5.9.12 is rock solid, I haven't tried any of the newer 5.9's yet, but I'll give .16 a shot and see if the issue is specific to 5.10.y.

Thank you so much; this solution sounds promising however, i cant get rid of this error message. I have uninstalled the nvidia driver from ponce's SBo-git repo and i can't see/find any other nvidia installed on my system but it just keeps popping up at ever ./nvidia-x-x.run

Thank you all for the suggestions. Whatever it was, it disappeared today with the latest kernel upgrade (5.10.3). At least I didn't have any problems so far, after several hours of testing. So, if you were thinking about reverting to the previous kernel version, maybe the better option would be to just upgrade to the latest one.

Glad to hear however, it didn't work for me.

Could you be more specific? What disappeared: the glitching? the system crash/freeze? did you uninstall the proprietary driver?

Sorry to hear that.

I first tried the proprietary driver, but it didn't help. I still had both screen glitching and occasional freezing (screen and keyboard freeze, fan goes wild).

Next, I uninstalled the proprietary, switched back to the nouveau driver and decided to wait for the next kernel upgrade. After the upgrade to 5.10.3, both glitching and freezing disappeared (or at least didn't appear in the next several hours of testing). If anything changes (hopefully it won't) I'll let you know, but everything looks OK now.
