To whom it could possibly concern, Here we go again. (see http://www.ussg.iu.edu/hypermail/linux/kernel/0512.0/0199.html for my first post) Really, is there anyone who could possibly figure out what's going on here? I'm not running any out-of-tree modules, and unlike last time, this is pristine 2.6.14.5. So at the risk of repeating myself, here's what happened: I did lsof -np 3999 several times (as it was hanging and I was wondering what was going on) The processes were in D and Z state and after a few had built up this oops was thrown. My config is attached.
