reassign 616726 linux-2.6 thanks The bug report you submitted is a kernel bug, so I am reassigning it to the "linux-2.6" package. Also, I suspect that solving this issue requires an intimate knowledge of the OCFS2 code, in which case you'd probably be better served by posting this to the OCFS2 users mailing list:
