I have seen this happen when  kswapd or kupdated hangs. This sounds a bit 
like it.
Sync hangs the box and I think the box locked because off the amount of 
processes waiting to get data written. I have seen this happen myself. If 
this happens sync/mount and some other utilities won't work and you can't 
get that data back.

Upgrading to a newer version is indeed a smart idea.
