Comment 1 Daniel Vetter 2012-07-09 22:42:30 UTC

We need the i915_error_state file from debugfs (only contains useful data if you haven't rebooted since the last hang) to diagnose this issue.

The OOPS is a bit worrying - can you please try to reproduce this on recent 3.5-rc kernel? Things are changing quite a bit in the relevant code, so only grabbing the OOPS some random stable kernel with unknown amounts of backported patches isn't too useful. Also, does the OOPS always happen together with the gpu hang?

Comment 2 freedesktop 2012-07-09 23:04:55 UTC

Have not rebooted.
Here is it: http://links.flashdance.cx/i915_error_state.txt

Well, the problem is that for many reasons I need to have this server
running, so I have limited time to break it. When I tried I couldnt even
get my own 3.3.1 kernel to boot. I guess stuff have changed in the last
few years when creating kernels. But this GPU problem has existed at least
since kernel 3.3.1.

No, the OOPS doesnt always happend. Sometimes its just GPU hung and X freeze
for about 2 sec. The screen gets black. Then everything is back to normal.
Examples:

When I logged in again, desktop effects was disabled, its called "compositing"
I belive. Thats bad but something I could live with, what I cant live with is
that I cant play any movies anymore when this happend. Also, gdm is also started
on a new tty. Before I had it on tty7 (moved it from tty1 that are default in CentOS nowadays).. And now its started on tty8 instead.

The only way I know to fix this, is to reboot :( And thats really tragic.
Is this GPU bug related to my compositing problem or is it something else?
I think you know this better than me...

Also, is it possible to reset this compositing WITHOUT rebooting?
Here is the i915_error_state file from what just happend
http://links.flashdance.cx/i915_error_state2.txt
However, it doesnt differ from the http://links.flashdance.cx/i915_error_state.txt file... very strange, shouldnt it be new debug error
state stuff in it when GPU bug happends the second time?

Comment 4 Chris Wilson 2012-07-14 09:17:08 UTC

Apparent hang in mesa, please make sure you have the latest drivers and see if you can identify the likely culprit.

Comment 5 freedesktop 2012-07-17 10:20:37 UTC

Ok.
Yes I have the latest drivers. CentOS 6.2 was updated to CentOS 6.3 recently.
Do you mean that the GPU hung problem is a mesa problem or that its two separate problems and just what I reported latest is a mesa problem that doesnt have anything to do with the GPU hung problem?

Comment 6 Chris Wilson 2012-07-17 10:27:03 UTC

The kernel is reporting that somebody hung the GPU and delivering the error state. That error state implicates mesa/i965 as the guilty party.

If you can reproduce on the latest drivers you have available, we will be interested in knowing the details.

Comment 7 freedesktop 2012-07-17 10:41:49 UTC

I see.

It hasnt happend for almost 6 days now but according my logs, it has happend before that it wasnt any problem for 6 days. Jun 26 -> Jul 3 is 6 days.

I'll wait and see for a few days and see if it happends again.

Comment 8 freedesktop 2012-07-19 05:52:27 UTC

Now it happend again.

Comment 9 Eric Anholt 2012-08-13 00:52:22 UTC

Are there specific steps to reproduce the problem?

Comment 10 freedesktop 2012-08-13 05:55:15 UTC

Sadly no. Its random.
Now it hasnt happend for 16 days, but I dont think its solved.
Its just luck that it hasnt happend.

Comment 11 freedesktop 2012-08-26 18:46:46 UTC

Happend again. Interesting, now I cant even cat /sys/kernel/debug/dri/0/i915_error_state it just says like this:
cat: /sys/kernel/debug/dri/0/i915_error_state: Cannot allocate memory

This is what the kernel says:

Cant use an newer kernel as the keyboard doesnt work at boot so I cant
write encryption pass.

Comment 12 Peter Åstrand 2012-09-03 07:05:54 UTC

I believe I have the same problem, reported here:

http://bugs.centos.org/view.php?id=5911

I have since tried tweaking my xorg.conf:

Section "Module"
        Load  "record"
#       Load  "dri2"
#       Load  "dri"
        Load  "glx"
        Load  "extmod"
        Load  "dbe"
EndSection

...

Section "Device"
        ### Available Driver options are:-
        ### Values: <i>: integer, <f>: float, <bool>: "True"/"False",
        ### <string>: "String", <freq>: "<f> Hz/kHz/MHz",
        ### <percent>: "<f>%"
        ### [arg]: arg optional
        Option     "DRI"                        "false"
        #Option     "ColorKey"                  # <i>
        #Option     "VideoKey"                  # <i>
        #Option     "FallbackDebug"             # [<bool>]
        #Option     "Tiling"                    # [<bool>]
        #Option     "LinearFramebuffer"         # [<bool>]
        #Option     "Shadow"                    # [<bool>]
        #Option     "SwapbuffersWait"           # [<bool>]
        #Option     "TripleBuffer"              # [<bool>]
        #Option     "XvMC"                      # [<bool>]
        #Option     "XvPreferOverlay"           # [<bool>]
        #Option     "DebugFlushBatches"         # [<bool>]
        #Option     "DebugFlushCaches"          # [<bool>]
        #Option     "DebugWait"                 # [<bool>]
        #Option     "HotPlug"                   # [<bool>]
        #Option     "RelaxedFencing"            # [<bool>]
        Identifier  "Card0"
        Driver      "intel"
        BusID       "PCI:0:2:0"
EndSection

Does not help. Any other options I can try?

Comment 13 Daniel Vetter 2012-09-03 09:32:38 UTC

Peter Åstrand, please file a separate bug report for your issue - I don't see any evidence that your gpu hang has the same cause as this one here. And mixing things up in this fashion generally leads to decent confusion. Thanks.

If anyone can reproduce, please file a new bug.
