Hello, I was wondering if we can get some help in resolving this bug. It was reported earlier and logged in bugme.osdl.org http://bugme.osdl.org/show_bug.cgi?id=4683 The problem is kernel oops at log_do_checkpoint() due to NULL buffer_head. This could be because of some race in journalling code for which I don't have much clue. There is kdump available for analysis as mentioned in the bugme.
