Bug 98706

If needed, I can test the patches to the kernel or X11 server.

However, I have to stick to X11 server 1.17.4 for another month or two, so I cannot update it as a whole. Still, I can try patches to it.

There were improvements pushed in kernel and Mesa (13)that will benefit to your system, so please re-test with latest kernel & Mesa to see if this issue is still occurring: mark as REOPENED if you can reproduce and RESOLVED/* if you cannot reproduce.

In parallel, assigning to Mesa product (please let me know if I am mistaken with this GPU Hang).

Kernel: 4.4.0-rc6-mainline
Platform: Ivybridge (pci id: 0x0166, pci revision: 0x09, pci subsystem: 17aa:21fa)
Mesa: 12.0.4

From this error dump, hung is happening in render ring batch with active head at 0x00dcf294, with 0x7a000003 (PIPE_CONTROL) as IPEHR.

We can note also: ERROR: 0x00000101
    TLB page fault error (GTT entry not valid)
    Cacheline containing a PD was marked as invalid

and in render batch: Unloaded PD Fault (PPGTT)

Yes, I will re-test it with Mesa 13.x and the mainline kernel 4.9 (or, do you suggest another git tree?), hopefully, later this week.

It is 4.8.7 on that system, actually.

Thanks Eugene, current mainline is fine :)

You are right, bad copy'n paste :^(. To be accurate this is : 4.8.7-nrj-desktop-1rosa-x86_64

I have updated Mesa to 13.0.1 and libdrm to 2.4.73 while keeping the kernel the same for now. No problem after resume so far. 

Will monitor the system for a couple days, let us see if the issue shows up again.

OK, several hibernate-resume cycles in 2 days - the problem haven't shown up. Let us assume Mesa 13.0.1 and/or libdrm update fixed it.
