Similar to http://bugzilla.kernel.org/show_bug.cgi?id=8473 .

Can you try Andrew's debug patch (at this URL):
Comment 3 Peter Clifton 2007-06-04 09:35:57 UTC
So far I've not been able to reproduce that Oops, or get any output from the
debug patch.

I'd been poking about a bit with lshw and gnome-session, (flicking between
console and X11 quite a bit) when it occurred before, and have not seen it since.
Comment 4 Alex Riesen 2007-06-10 14:18:14 UTC
I had the Akpm's patch (and since 2.6.22-rc3 there is some diagnostic with a
stack dump there). Haven't seen the bug since the -rc3.
Comment 5 Alexey Dobriyan 2008-09-08 22:41:41 UTC
I remember exactly same backtrace and it was flipping tty fops.
