S510 with 12.04 may halt in less than 24 hours. But if we disable RC6, it works quite well. Now ctf enables RC6 again, let's see how it goes this time.

[Jesse Sung (wenchien)]

After enabling RC6, S510 halts after a 30-minute idle.

[Jesse Sung (wenchien)]

Ref: https://bugs.launchpad.net/bugs/1002170

Hi,

Lenovo ThinkCentre S510 (SandyBridge i5-2500S) may hang after idling for some period of time. This may be related to rc6 since that if I add i915.i915_enable_rc6=0 to boot parameter then this issue is gone.

This issue also happens on kernel 3.4.

A screenshot when system hangs:
https://launchpadlibrarian.net/105661463/Photo%2012-5-18%2017%2038%2038.jpg

If there's any other information needed, please kindly let me know.

Thank you.

[Jesse Sung (wenchien)]

Tested with mainline build kernel 3.4 in kernel-ppa, this issue still exists.

[Daniel-ffwll (daniel-ffwll)]

Please attach dmesg with drm.debug=0xe added to your kernel commandline. Also, how dead is the system? I.e. does network/ssh still work, does the magic SysRq to reboot still work, or is it a true hard-hang? And can you try to wire up netconsole so that we could have a peak at the last breaths of the system before it goes down?

[Jesse Sung (wenchien)]

netconsole output

Hi Daniel,

Please find the attached file for netconsole output.

When it hangs, neither SysRq magic nor network/ssh works. From ssh terminal I can tell that it died after 57 minutes, but the last entry in the log is at 1787.315652, so there's no log when the system goes down.

[Daniel-ffwll (daniel-ffwll)]

Can you also attach dmesg so that we have all the interesting lines from boot-up with drm.debug=0xe, too?

[Jesse Sung (wenchien)]

dmesg is attached.

Thank you.

[Jesse Sung (wenchien)]

Hi Daniel,

Is there anything I can do to get more info about this issue?

[Daniel-ffwll (daniel-ffwll)]

I'm running a bit low on ideas, but one thing would be to stop all drm clients (i.e. X) and check whether it still hangs. We still need to load the drm/i915.ko driver, because only when we load and enable rc6 can the cpu die actually reach the lowest power state, i.e. I want to check whether this might be an issue outside of the gpu, only brought to light due to the low power state.

[Jesse Sung (wenchien)]

Daniel,

Tried with a normal boot, and stopped all X related processes. System hangs after 15 hours.

[Chris Wilson (ickle)]

Ok, what happens if the i915 is never loaded at all? Try something like adding
blacklist i915 to modprobe.conf, or append i915.noload to your kernel commandline.

[Jesse Sung (wenchien)]

Hi Chris,

By adding i915 into blacklist and using text mode, system runs without any problem and has "2 days, 19:15" uptime so far.

[Jesse Sung (wenchien)]

Please try http://people.canonical.com/~jesse/lp1002170/ and see if this issue still exists.
Thank you.

disable rc6 for some models

Hi Daniel and Chris,

Since there's another snb machine does not work well when rc6 is enabled ( https://launchpad.net/bugs/1008867 ), maybe we can just disable rc6 for these machines to make them at least work?

[bwidawsk (bwidawsk)]

By any chance, does this patch help?
https://patchwork.kernel.org/patch/1363021/

[Jesse Sung (wenchien)]

Hi Ben,

No, this patch does not help. System hangs after 2 days and 6 hours.

[Jesse Sung (wenchien)]

Hi,

What do you think of the patch in #c10 ? Should I send it to mailing list also?

[Daniel-ffwll (daniel-ffwll)]

I think it'd be much better to figure out the root cause and fix it - since likely these rc6 issues don't have anything to do with these models specifically, we just haven't figured out yet what the real problem is.

[Jesse Sung (wenchien)]

Hi Daniel,

Then I guess it's better to have a new bug entry for lp1008867. :)
https://launchpad.net/bugs/1008867
I'll create one later.

Also, please could you suggest what I can do to get useful info for finding out the root cause?

Thank you.

This bug is awaiting verification that the kernel for Precise in -proposed solves the problem (3.2.0-32.51). Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-precise' to 'verification-done-precise'.

If verification is not done by one week from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!

Hello, I have a similiar issue. My system ocassionally hangs with the same screen corruption, plays audio in a loop for about a second and then the laptop fan revs up.

It happens more often when playing some flash videos. Sometime the system hangs twice a days, sometimes after a week. I'm going to try disabling rc6 after next crash.

It's a MSI CR640 Sandy Bridge laptop with i3-2310M and:
