Ok. I had been planning on moving to 2.6.9 and 1.9.3 as soon as both
were final. Guess I can try the RC releases though. :)

Ah, right, didn't show up in messages but was in syslog:
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]

Well, log_do_checkpoint doesn't appear to be very long.. Here's the
objdump -d from it (I also wasn't 100% sure where the location of the
oops was in the objdump..):
