Bug 94021

I can often trigger the bug by opening maps.google.com in Firefox 44
and then rapidly zooming in/out and panning around the map.

Appears to be duplicate of https://bugs.freedesktop.org/show_bug.cgi?id=93049

Though I've been experiencing this too and I'm on kernel 4.4.2-301.  It seems to happen whether using Fedora repo's Intel driver or Intel's own repository.  Seems this isn't over yet.

Hmm after scouring the forums and trying various kernel options I seem to have stabilized mine a bit with "i915.enable_rc6=0" as recommended on Intel community site.  Annoying as this is far from my first Skylake issue.  May as well have named the series Skyflake.

I was mistaken on the duplicated bug, 96318 is not duplicate of this one

There were workarounds on SKL pushed in kernel (more recent than yours 4.4.0-8.g9f68b90-default), so please re-test with latest kernel to see if it has some benefits on that work.

In parallel, assigning to Mesa product.

From this error dump, hung is happening in render ring batch with active head at 0xf031f498, with 0x79000002 (3DSTATE_DRAWING_RECTANGLE) as IPEHR.

crash dump

I'm experiencing simillar problem since I built my pc ~10 months ago. It happens when I'm using rdesktop connected to server running windows server 2008 R2. It can happen multiple times a day.

Single gpu hang is not a big problem, because it can recover, but if it occurs multiple times in a row, then it kills my session which is extremely annoying.

I upgraded my archlinux 3 weeks ago to:

Since then I was unable to reproduce the error.

My guess is that you've gotten bit by a more recent issue.  Mesa master / 18.0 ought to work, and the fixes should hopefully hit stable releases before too long.

Similar situation here:

[ 5087.853310] [drm] GPU HANG: ecode 9:0:0x86dffffd, in Xorg [862], reason: Hang on rcs0, action: reset
[ 5087.853316] i915 0000:00:02.0: Resetting rcs0 after gpu hang

[ 5125.828738] i915 0000:00:02.0: Resetting rcs0 after gpu hang

Then X restarts (without log).

CPU: i3 6320

$ lspci
00:02.0 VGA compatible controller: Intel Corporation HD Graphics 530 (rev 06)

Very reproduceable when editing texts in LibreOffice Impress 6.0.1.1 (other similar versions should also trigger). Other applications do not seem to trigger the problem.

I believe the problem started a few months ago and happens with kernel 4.9. But I cannot remember clearly.

Adding "i915.enable_rc6=0" alone to boot parameters does NOT fix the problem. Adding "intel_iommu=igfx_off" does seem to fix it.

However, I wonder whether the bug is specific to this mesa version. The bug first showed up a few month ago, and I am on Debian testing. Chances are the bug spans multiple versions, I think.

There is this report https://bugs.freedesktop.org/show_bug.cgi?id=105195#c5 where is mentioned that downgrading to mesa 17.2.4 fixes the issue, could you confirm if your case is the same and, if possible, try mesa 18rc4?
Thank you.

17.3.6 is out, and should fix this as well.

Seems 17.3.6 from Debian unstable has fixed my case.
