Package: kernel-image-2.6-k7
Version: 101
Severity: normal

I wasn't doing anything with the machine in question - it's a server, so
I definitely wasn't fooling around with the hardware.  The symptoms are
that the hotplug process seems to totally lock up - even trying to read
from its proc/ entry causes problems, meaning that ps, top and friends
hang.

Looks similar to this:
