[Bug 213053] Re: Totem is 'uninterruptible'

This is not Hardy-specific. Running Intrepid. It's a kernel bug, and still in 2.6.7.
uname -a: Linux ricardo-desktop 2.6.27-10-generic #1 SMP Fri Nov 21 12:00:22 UTC 2008 i686 GNU/Linux.

It's the same thing here. Totem in uninterruptible sleep, can't be killed.
The kernel is stuck in exit_mm, after scheduling out the process.

I tried to attach gdb to it, but gdb is [code]wait[/code]ing for totem.
Try to SIGTERM gdb, and it asserts from "linux-nat.c:1072".
(Not sure if this will help, though...)


The following message is output to /var/log/syslog, /var/log/kern.log and /var/log/messages
every 2 minutes (sometimes, it's printed more than once at one time):
