Since my last system update a week ago, the nvidia.ko module has been spamming the journal with the following:
NVRM: GPU0 dispcmnCtrlCmdSystemGetVblankCounter_IMPL: invalid head number!
It comes in bursts, not constantly, but dumps dozens per second when it does. I estimate 8.5M records in the attached bug report. Unfortunately, it looks like the SystemD journal cannot be configured to ignore/drop messages by pattern, so I need to find out how to silence the driver if, as it seems, this is not a serious error. (The system/desktop/display runs normally; the only way I can tell there is a problem with the logging is that the journal files are immense and being rotated much more often than usual.)
Thanks for any help.

I experienced this on my Fedora 43 with MATE-Compiz and rpmfusion-loaded driver 580.119.02-1.fc43.x86_64

Added: The messages seem to correspond to when the monitor is dark (power management). Association with the crash I experienced is not proven, only associated in time.
I can reliably trigger this error by running xset s activate; xset s off which puts my monitors into low power/sleep mode without putting my computer to sleep.
