See http://bugzilla.kernel.org/show_bug.cgi?id=8472.

A more general solution is to disable MSI for the VIA VT3351 (used by
the Asus M2V).  I attempted to do this in the -stable tree with
http://lkml.org/lkml/2007/5/26/167, but it was shot down because the
patch isn't upstream yet.

Unfortunately, I can't submit it upstream because the enabling
patch hasn't yet been applied upstream by the PCI maintainer. My
request for info on the status of the patch went unanswered.
http://lkml.org/lkml/2007/5/19/74

The enabling patch was submitted by Tejun Heo 9 May.
http://lkml.org/lkml/2007/5/9/213

It was applied to -stable (2.6.21.2) 23 May.
http://lkml.org/lkml/2007/5/23/385

It has not yet been applied upstream.  When it is, I'll push the atl1
MSI patch.

Thanks a lot for the note, Greg.  I appreciate it.  I'll be patient.
