Hi,
I've noticed some strange soft lockup behaviour on my system (please see the attachment). Soft lockup appears to be caused by kswapd0 process. It seems to me that in both cases this error occured when I used "git fsck --full" or "git gc" commands.
I've got the same problem on 3.2.6-3.fc16. Any ideas what might be happening? I turned off the swap partition to see if this help.

I've got the same problem on 3.2.6-3.fc16. Any ideas what might be happening? I turned off the swap partition to see if this help.
Is this happening inside a virtual guest ?

No, this system runs on Intel Atom 330 D945GCLF2.

No, this system runs on Intel Atom 330 D945GCLF2.
This time it looks different - it happened while system upgrade. Swap is disabled.
