Vedran,
Can you try this patch and see if it solves your GPU hang issues? I still
haven't been able to reproduce it, but I believe I may just be getting lucky.
Nope, with this one it's even worse.
Before after the initial hang glretrace would finish "normally" (I
guess, though I've seen some screen corruption with 2D font rendering
afterwards), but with this patch the hangs are happening multiple
times.
As I've said earlier, I'm not using an accelerated compositor, just simple LXDE.
DDX is latest from git, kernel is 3.9.4, and I've confirmed the bug
with just simple glxgears.
I can reproduce it every time after a clean reboot.
Okay, I was able to reproduce this with a clean reboot and starting X
with SNA, xterm, and then glxgears, with nothing else running. I did
later see font corruption in Firefox. I was also able to reproduce the
hangs with UXA.
I've pushed a revert for "i965: Disable unused pipeline stages once at
startup on Gen7+." Does this fix the GPU hangs for you?
