Periodically I’ve been seeing the 346.47 driver hang when playing video on a GTX 980. Everything freezes for a good 10 seconds or so, then resume for an instant, then freeze up again. This shows up in the kernel log when this happens:
[143776.885977] NVRM: GPU at PCI:0000:01:00: GPU-199c86dc-fdf0-d1c8-37a2-d9e525b5d155 [143776.885981] NVRM: Xid (PCI:0000:01:00): 31, Ch 00000010, engmask 00008100, intr 10000000
The only way I’ve gotten out of it is by killing VLC via Alt-F4 while it’s frozen (the key strokes are processed when things resume briefly).
I’ve seen this behavior occur on both Linux 3.19.3 and 3.14.37. Any ideas about the cause?
I believe it’s using the VDPAU output module for video.
