[Xen-devel] qemu-dm segfault installing FreeBSD 32 bit FV on a heavily loaded machine

["Richard W.M. Jones" <rjones@xxxxxxxxxx>]

I'm seeing a segfault in qemu-dm when installing FreeBSD 6.2 32 bit 
fullvirt on a 64 bit 4-core AMD machine.  The segfault only occurs (or 
at least is much more common) when the machine is heavily loaded.  In 
this case, doing 'make -j 4' kernel compile in the background.  There 
are no other domUs running.
The symptom is that while FreeBSD is downloading and installing 
packages, qemu-dm segfaults with dmesg output like this:
qemu-dm[10011]: segfault at 0000000000000000 rip 0000000000000000 rsp
0000000041400c18 error 14

Xen 3.1 from xen-3.1-testing.hg which I cloned this afternoon.

Fedora 7 with all latest updates applied; in particular the 
2.6.20-2925.8.fc7xen kernel.
I started a Fedora BZ entry for this here:

https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=240009

It seems similar, but not the same as this: 
http://bugzilla.xensource.com/bugzilla/show_bug.cgi?id=542, but note 
that I've only got one FV domain running (indeed only one domU running 
at all).
Rich.
