** Description changed:
- No matter if I tried it with 410.x series, 415.x series, 418.x or 430.x
series after an S3 (suspend to RAM) ... everything that needs CUDA and GPU
acceleration stop working. will update with appropriate dmesg output.
- Fun fact: I just tried adding info putting this system into S3 and after
waking up all the CUDA and driver related stuff also worked again ...
- this is weird !!
+ I you watch a movie that uses CUDA/VDPAU (nvdec for mpv, vdpau for VLC)
decoding with {410,415,418,430} and pause the movie and do a S3 (suspend to
RAM) ... everything that needs CUDA and GPU acceleration stop working. will
update with appropriate dmesg output.
+ Maybe VDPAU can recover but CUDA can't
+ Got the extra outut from dmesg - it prints graphics cards serial no and bus id
+ ```
+ NVRM: Xid (PCI:0000:1f:00): 31, Ch 00000003, intr 10000000. MMU Fault: ENGINE
HOST6 HUBCLIENT_HOST faulted @ 0x1_001a1000. Fault is of type FAULT_PDE
