When I use GPU acceleration on Flash on Firefox, the gpu resets itself frequently. From journald:

kernel: [drm] stuck on bsd ring
kernel: [drm] GPU crash dump saved to /sys/class/drm/card0/error
kernel: [drm] GPU hangs can indicate a bug anywhere in the entire gfx stack, including userspace.
kernel: [drm] Please file a _new_ bug report on bugs.freedesktop.org against DRI -> DRM/Intel
kernel: [drm] drm/i915 developers can then reassign to the right component if it's not a kernel issue.
kernel: [drm] The gpu crash dump is required to analyze gpu hangs, so please always attach it.

Crash dump from /sys/class/drm/card0/error

Sorry for slow response. Are you using libvdpau-va-gl to get hardware accelerated flash?

Yes, I had been using libvdpau-va-gl back then. For the last months I had Flash disabled. I will enable it back with GPU acceleration (I still use the same laptop) and I'll report back.

I have enabled Flash for the last month, and so far, this problem has not resurfaced, everything seems normal.

According to comment #5, Closed this bug as 'WORKSFORME'
