Describe the bug
Driver fails to allocate any memory for hw decoding. Even is memory is free. Logs from dmesg says that.

BUT next try it will be okay. Issue is not consistent. Sometimes it may happen right after suspend wake up.
To Reproduce
Try to use player with hardware decoding support (mpv, firefox, etc).

Fixing this means either freeing VRAM, tuning your workloads, updating drivers, or hardware upgrades.

I’ve found a setup that greatly improves stability:
- Boot in UEFI mode with CSM disabled, and enable Resizable BAR.
- Add the kernel parameters
cma=2048M nvidia_drm.modeset=1to GRUB. - If you use ZFS, cap ARC to a reasonable size for your RAM—for example,
zfs.zfs_arc_max=8589934592(8 GiB). - Before you activate the GPU, keep at least 6 GiB of free system RAM. The driver often fails when caches and buffers consume most of the memory, suggesting it has low allocation priority. When memory is tight, running
echo 3 > /proc/sys/vm/drop_cachesfrequently resolves the issue. - And this is not a VRAM issue.
The driver itself seems to be running out of kernel memory. Definitely not a VRAM issue.
Looks like not a VRAM issue indeed. Not good news, because I have 32 gigs of RAM - this is strange
I'm seeing the same problem with a 1660 on debian. I'm only using the GPU for Plex and Immich transcoding, nothing fancy. Logs attached below.
This was happening on 575.51.02, I don't remember what the previous version I installed was so for now I rolled back to 570.153.02.

There's a chance this happened because the GPU woke up for a very short time, considering the primary GPU is the AMD CPU's.
The driver has a kernel memory page leak. nvidia_pte_cache in slabtop looked pretty suspect.
I seem to be still getting this issue on driver 580.82.07 I get 100s of this:
NVRM: gpuHandleSanityCheckRegReadError_GM107: Possible bad register read: addr: 0xbb0080, regvalue: 0xbad1e5a0, error code: Unknown SYS_PRI_ERROR_CODE
Then a few of these:
NVRM: nvAssertFailedNoLog: Assertion failed: (status == NV_OK) || (status == NV_ERR_GPU_IN_FULLCHIP_RESET) @ mem.c:180
Then it crashes with a few of:
