Hi,
I'm regulary suspending my notebook. After resume skype typically produces a
lot of processor load when trying to call somebody and I have to restart it
to make it work again. Today, with a new kernel, skype seems to cause a soft
lockup resulting in a freeze for a few seconds:
BUG: soft lockup detected on CPU#0!

I know, skype is closed source and cannot be debugged, but even a closed
source userland program should not be able to cause a lockup. Is the
information given above useful to find the problem inside the kernel? If not,
what can I do to provide better debug information? I'm using a vanilla
2.6.17.11 kernel:
Linux ibm 2.6.17.11 #1 PREEMPT Sat Aug 26 18:55:43 CEST 2006 i686 GNU/Linux
