>Description:
I am experiencing some unspecified lockup/deadlock with 7.2 on AMD64, roughly every two weeks. The <http://shell.sh.cvut.cz/~wilx/textdump.tar.0> is text dump of the event obtained from DDB. It seems incomplete because the textdump capture area seems to be too short and there were many cron jobs running ifconfig every five minutes stuck.

>How-To-Repeat:
Dunno.
>Fix:
Dunno.
