HI all,
I've just compiled 2.6.23.8 from kernel.org sources and I getting a
bunch of these soft lockups detected. This seems to be similar to
the problems reported here:
http://lkml.org/lkml/2007/11/19/345
but I am not as far as I am aware using the ondemand governor.
> cat /proc/acpi/processor/CPU0/info
processor id:0
acpi id: 0
bus mastering control: no
power management:no
throttling control: no
limit interface: no
What is suspisious is "Clocksource tsc unstable".
Dump from dmsg follows. Any light people can shed on this much
appreciated.
Cheers,
Erik
