Bug 123137

Created attachment 100200 [details]
oops output

Oops output when this happened.
The system load was probably 3ish.
Uptime was less than a day (due to an un-related reboot)

There were quite a few ext3 related changes in later kernels.
I'm not guaranteeing they fix this problem, but it makes more sense to
test -358 if you can.

No information given about later kernels, so closing: please reopen if
you can still reproduce this problem.

I've been bit by this problem under both 2.6.8.1 and 2.6.9 now.  I
don't have an oops from 2.6.9 yet (unfortunately, I'll check once I
get home and see if it got logged over the serial console) but here is
one from 2.6.8.1:
Assertion failure in log_do_checkpoint() at fs/jbd/checkpoint.c:361:
"drop_count != 0 || cleanup_ret
+!= 0"
kernel BUG at fs/jbd/checkpoint.c:361!
invalid operand: 0000 [#1]
