No, it's an immediate hard lockup. It occurs right after a file writefile,
and the file that's supposed to have been written does not get written.

Is there somewhere I can look after I reboot and it gets done fscking my
drive? btw, about 20% of the time it does such serious damage that it puts
me in maintenance mode on reboot. (I did a *lot* of rebooting to get the
information for the bug.)

i'll give it a shot.
