The previous kernel had been running fine for some time, and now at night
around the running of periodic, the box will 'periodically' crash. It does
not seem to do it each night, but almost every other night and always just
after 3am when periodic runs. I can never get a crash dump, and I had to
hook up a serial console to capture this at night. Also, I cant seem to
force the issue by running periodic by hand. But, like I said, it always
seems to happen a few minutes after 3am. (No, nothing else is scheduled to
run then and no other boxes do anything to it at that time either)

Any ideas how best to track this down ? There seem to been some commits on
