I’ll follow up with the full NVIDIA debug log once I’ve gone through its contents, but looking to see if anyone else has experienced this issue. Have had the card for a year and its been working fine under Windows 7. On Linux, however, seeking in VLC seems to freeze X (assumed because windows aren’t responsive and keyboard events get queued). SSHing in and kill -9’ing VLC clears it right up. This on Arch Linux with everything up to date and has been the case for 2 months now.
Kernel logs only a single error 31 when it happens:
