Random shutdowns with linux 3.11.6

el mariachi · 2013-10-28 19:42:14

I have been experiencing random shutdowns since some time ago. I cannot say for sure after which upgrade, but I'm positive it only occurs in the 3.11 series.
My laptop simply shuts down (not a reboot!), the battery led lighting up for a second. After this, pressing the power button doesn't "wake up" the screen, which remains black and without any power (i.e. not even the backlight turns on). I press the power button once again, for a hard shutdown, and then everything works again. I cannot see a pattern -- sometimes this happens as soons as I boot into X, other times it can be after hours, even days.
Booting with the vanilla ARCH kernel never also elicits this behaviour.
My laptop is a Dell E5400.

There could be an error message somewhere from before the problem. In which logs should I look?

Might be a good idea to post this to ck's blog; he might answer you and other users might as well.

will do!

Today, for the first time, my laptop powered down with the ARCH kernel. The bios error log had an entry saying "Powerdown reason: WDT" why is the WDT shutting my computer down? Which log should I check when I boot correctly again?

WDT = Watchdog Timer , https://en.wikipedia.org/wiki/Watchdog_timer .

kernel.log would be the place i'd look , but journalctl should also be able to show events from just before the shutdown.

I noticed my keyboard/mouse sometimes freeze for a second (this can happen before the whole thing shuts down).
dmesg

Hi,

Ok I'm not using arch, but I am running a custom built 3.13 kernel (intel drm next branch) on a Dell 7440 and in the last few days after using the kernel for about 2 months with no issues, I started seeing *exactly* the same symptom of the laptop screen just going blank at random times. Because I usually have an enternal monitor plugged in I know its just the screen and not the whole laptop shutting down because the external monitors are not affected.

The common thing seems to be that I see the line:
dell_wmi: Received unknown WMI event (0x0)

in my dmesg too though I'm not 100% certain it correlates exactly with the times the screen switches off yet.

There hasn't been any followups to this, so I 'm guessing this problem stopped for you?

If not perhaps we can pool our data on this and submit a bug report to https://bugs.freedesktop.org ?

thanks,
Maks.
