jbd2 debugging patch
The jbd2-checksum-debugging patch adds two options which can be added to the
boot line. The first, jbd2.xsum_debug=1, will print two additional kernel
messages when replaying a journal that will help debug checksums. The second,
jbd2.ignore_xsum=1, will cause jbd2 to ignore any checksum errors.
If you can come up with a repeatable test case, it would be useful to apply
this patch and then add "jbd2.xsum_debug=1 jbd2.ignore_xsum=1" to the boot
line. Then let me know (a) if the problem goes away when you add the boot
command-line options, and (b) give me the dmesg output either way.
Thanks!
