This sounds similar to what I was seeing with bug #800, only I don't
think I had taskfile IO enabled. Another person I talked to had some
success by enabling PIIX I think, but that did not work for me. The
only workaround that worked for me was to disable highmem support. The
link is: http://bugme.osdl.org/show_bug.cgi?id=800. I havn't tried it
this week, but I don't think it's been fixed yet.

Thanks,
Paul Larson
