Sources have been csup'ed a couple of days ago. System rebuilded and installed as usual (make world + make kernel + etc). I'm using new 7.2 features - Superpages and "The shared vnode locking for pathname lookups in the VFS(9) subsystem". Today, while running portupgrade -a, I got two kernel panics. First panic (12) I got using kernel without DEBUG options in, but second panic (13) with DEBUG - so I can provide kgdb bt to only last panic.
