The only reproducable way I have of triggering it is by doing multiple inserts into phpmyadmin on lighttpd+fastcgi php5 + mysql51-server, though this isn't the only thing which triggers it, just the only one which is semi reliable. I've also reproduced this on another machine, set up specifically to rule out any machine specific problems (as they have different drive controllers, one uses gjournal, etc). I inititially built a kernel with SW_WATCHDOG, and attempted to use watchdogd and DDB to get an output from show locks, but the watchdogd hasn't panicked the machine, so at least devfs is still unlocked; I'm not able to get physical access to the machine until monday. The bug was introduced as far as I can tell, between 7.1-BETA2 and 7.1-RC1. Any suggestions on what I can test for tommorow?
