[Xen-devel] segfault in dom0

[Jody Belka <lists-xen@xxxxxxxx>]

Just finished copying 135 gigs of files into my dom0 system over
the network using smbclient. No errors occured during the copy.
Immediately afterwards i tried to run a find command, but it's
segfaulting on me:

<1>Unable to handle kernel NULL pointer dereference at virtual address 00000000
 printing eip:

I've tried running find a few times, and the only differences each time
are in edi/ebp/esp/stackpage/stack/pid

I'm currently running rev 40f41ae00utn5d2f3tlNLcvG_QhiBA from 2004-07-13 
17:24:48

This also happened to me on an older rev, but i was messing about with the vmmon
stuff at the time, and i also wanted to move up to a newer rev to see if that
fixed things before saying anything. Now, last time the find worked again after
a reboot, but that's obviously no good. For the moment this time i've just left
things as-is right now.
