I'm getting frequent system crashes (every few hours or so) and it seems

down. The screen freezes and colours stream across it. Often after I
reboot the BIOS logo is mangled too until the first modeset. The crash
seems to be happening in nv50_fb_intr() in nv50.c.
I'm not sure if this is related, but the system now often freezes on
suspend or resume since I switched from using the old (recently
abandoned) proprietry NVIDIA drivers, again both with 5.2 and 4.19
kernels. Blacklisting the nouveau driver doesn't seem to fix it however,
though I guess the graphics card could still be causing issues in some
other way? I never had problems with suspend and resume before.
Any suggestions about how I could debug this further?
Is it really a software problem (does it still work fine with proprietary
These nVidia chips are known to fail and corrupt BIOS logo suggests that.
