[Karol Szkudlarek]

I'm debugging suspend problems with my laptop on ubuntu 12.04 LTS via:

sudo sh -c "sync; echo 1 > /sys/power/pm_trace; pm-suspend"

During suspend after dmesg > dmesg.txt I noticed that kernel module mac80211 crashed with the following stack trace:

Karol Szkudlarek, thank you for reporting this bug and helping make Ubuntu better. Could you please unplug all your USB devices from the laptop, restart, perform the test mention in https://wiki.ubuntu.com/DebuggingKernelSuspend and attach your dmesg.txt to this report as a separate attachment?

[Karol Szkudlarek (karol-mikronika)]

I've done as wrote in https://wiki.ubuntu.com/DebuggingKernelSuspend.
On my laptop pm-suspend crashed laptop and I have to manually boot up and after it I've created dmesg.txt. Please look at attachement.

[Karol Szkudlarek (karol-mikronika)]

Christopher,

in my dmesg I've found: Magic number: 0:418:499, how can I obtain more info about?

I've attached today crash kernel... log of crash (BUG: scheduling while atomic)...

[Karol Szkudlarek (karol-mikronika)]

And current dmesg.

[penalvch (penalvch)]

Karol Szkudlarek, thank you for providing the requested information. As per http://www.dell.com/support/drivers/us/en/04/Product/latitude-e6510 an update is available for your BIOS (A13). Could you please update to this and comment if this changes anything?

If not, could you please test the latest upstream kernel available following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Please do not test the kernel in the mainline kernels archive directory daily folder, but the one all the way at the bottom. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags:
kernel-fixed-upstream
kernel-fixed-upstream-VERSION-NUMBER

where VERSION-NUMBER is the version number of the kernel you tested. For example:
kernel-fixed-upstream-v3.7-rc1-quantal

This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag:
needs-upstream-testing

If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-VERSION-NUMBER

As well, please remove the tag:
needs-upstream-testing

If you are unable to test the mainline kernel, please comment as to why specifically you were unable to test it and add the following tags:
kernel-unable-to-test-upstream
kernel-unable-to-test-upstream-VERSION-NUMBER

Please let us know your results. Thank you for your understanding.
