$ git describe

No more page flip reports in the logs (I had similar output in 4.6-rc5 as listed in eg id=94572)

But GPU HANG still present. Steps to reproduce
- start X
- move some windows around, maximize/minimize scroll firefox window and
  within minute or so GPU got stuck

On plain kernel 4.5.0 seems fine, not managed to get gpu hang after similar steps.

Attached tar file containing dmesg output with drm.debug=0xe0, card-error, xorg.0.log

For bisection: (assuming this is the same as bug #96499)

This bug is present in the kernel currently shipping with Arch Linux:
Linux limbo 4.6.2-1-ARCH #1 SMP PREEMPT Wed Jun 8 08:40:59 CEST 2016 x86_64 GNU/Linux

I have downgraded the kernel on my machine and can confirm that the bug is not present in:
Linux limbo 4.5.4-1-ARCH #1 SMP PREEMPT Wed May 11 22:21:28 CEST 2016 x86_64 GNU/Linux
Comment 3 Jim 2016-06-25 10:00:27 UTC 
On kernel 4.6+ /  4.7-rc4 this issue appears to have been fixed. At least can't reproduce it anymore.

closing issue. If it happens again, please reopen.
Comment 5 Günther Noack 2016-09-09 06:04:37 UTC 
I still had this on 4.6.2-1 shipping with Arch Linux (as noted above),
but can't reproduce with 4.7.2-1.  Thanks for fixing!
