kernel 3.10.1 - "NMI received for unknown reason"

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi all,

starting a virtual machine (Debian sid) with KVM on my host running
kernel 3.10.1 (Debian 3.10-1-686-pae) produces these messages:

[  765.522920] Uhhuh. NMI received for unknown reason 31 on CPU 0.
[  765.522927] Do you have a strange power saving mode enabled?
[  765.522930] Dazed and confused, but trying to continue
[  770.487732] Uhhuh. NMI received for unknown reason 21 on CPU 0.
[  770.487740] Do you have a strange power saving mode enabled?
[  770.487742] Dazed and confused, but trying to continue
[  846.340966] Uhhuh. NMI received for unknown reason 31 on CPU 1.
[  846.340973] Do you have a strange power saving mode enabled?
[  846.340976] Dazed and confused, but trying to continue
[  847.563023] Uhhuh. NMI received for unknown reason 31 on CPU 0.
[  847.563029] Do you have a strange power saving mode enabled?
[  847.563032] Dazed and confused, but trying to continue

I can disable the messages (echo 0 > /proc/sys/kernel/nmi_watchdog) and
the host and the virtual machine are running as usual.


Host CPU: Intel(R) Core(TM) Duo CPU L2400



Regards,
Stefan
