This may possibly be caused by filesystem inconsistencies. Can you try reiserfsck and seeing if there are any corruption issues?
try his suggestion and if this is still falling apart, try upgrading your kernel if that fails, the kernel.org site has a bugzilla where you can report this
as I have same/similar problem, I've created bugreport in kernel's bugzilla - http://bugzilla.kernel.org/show_bug.cgi?id=2984
