Unstable GUI after upgrade to LInux-5.9.1.artix


A week or two ago I upgraded and got random crashes and GUI lockup.  Runs well, and then the mouse slows down to a crawl.  After research on the internet I downgraded to 5.8.14 from cache.  I was able to check the error log and got the following errors (xxx is short for addresses):

nouveau 0000.01.000 : fifo:  PDMAO: xxx [] ch 7 [ xxx eadedCompsitor [3219]] subc mthd 0000 data 0000000
nouveau 0000.01.000: gr: DATA_ERROR 000000c [INVALID BITFIELD] ch 7 (xxx eadedCompsitor [3219]] subc 0 class 9297 method 1618 data xxx

Unfortunately I only have a cellphone pic of the file, but I can supply the missing addresses if needed.

Other info: downgrading to 5.8.14 fixes the problem and I have my great Artix Linux running flawlessly (big fan).  I'm using an older video card, NVDIA GEFORCE GTX 570 rev a1 by MSI. Using OpenRC for init.  xfrce desktop.  I'm not using the NVDIA driver.

I'm intermediate on Linux skill level.  I'm a hobbyist C programmer and can get around in console mode, but not very expert on Linux.

I've been disabling Linux kernel updates, but that is not a permanent fix.  I noticed the latest is 5.9.2.  I don't know if that will fix things, but I'm willing to give it a try.

Thanks for your help.

The log file still exists.  Here's another snip:

Note errors are gone after downgrading the kernel.

Upgrade to 5.9.2.
Kernel bug probably

I'll give it a whirl tomorrow.  It's definitely not Artix.  It's the linux kernal.
