Created an attachment (id=35215)
gtt flush failures (not fatal)

I have attached the flush failures found in dmesg (probably not related to the overlay crash) and the DRI debugfs after a crash happening when watching videos.

Looks like the overlay bug is not yet fixed. I had to watch the entire video collection of The Rockets, but finally I got an overlay filled with a nice blue, music still playing but Xorg inevitably dead. I could access a VT and take the dump, but any further attempt to restart Xorg was failing miserably.

Xorg was being filled indefinitively with these lines:

(EE) intel(0): Failed to submit batch buffer, expect rendering corruption or even a frozen display: Input/output error.

Nothing else was relevant there.

I think the flush failures are not tied to the overlay crash (I also have them when the system doesn't crash), but anyway I have added them here.
