Public bug reported:
Hi,
I encounter a random bug when suspending my computer : everything suspends
properly when I press the sleep button on the keyboard, but sometimes the
computer freezes when I wake it up (by hitting the power button). So I have to
power off the computer by long press on the power button, or reset the computer.
I tried to suspend with the pm-suspend command, I got the same result.
I tried to suspend through a TTY, and here I was able to get some logs (I took
a photo of the log, attached to this bug report).
The error message was the watchdog detected a hard lockup on the cpu (8 core
cpu, so I got several times the message).
The faulty software seems to be systemd-udevd, according to the trace I got. I
googled a bit the problem, but wasn't able to very usefull information
I wasn't able to find anything about the message I saw on the screen in
the log files. No record at the time of the freeze. That really
surprised me.
I noticed also this problem related to suspend : I use virtualbox and if
I suspend computer, resume it and try to launch a VM after, I can't get
it running properly : it is very slow and I have to reboot the compter
to get it working properly. And I noticed also if I have used a VM and
after I suspend the computer, I am almost sure I'm gonna have a freeze
when I wake the computer up. Maybe is there something related ?
This problem happens randomly but I didn't find anything to reproduce it.
Here is the configuration of the computer :
-mother board : MSI h77ma-g43
-cpu : intel core i7 ivy bridge series
-ram : 16 gb
-using onboard soundcard and video card
-1 hdd 1.5 tb on sata 3
-another 1 tb hdd on sata 3
-bluray/dvd burner on sata
Using Kubuntu 13.10 x64 everything up to date.
Does anybody get the same or a similar problem ?
If any more information is needed, please feel free to ask.
