I'm also getting the same error. I don't have anything with serial

Thanks.

Wei does this give any hints to this bug? This is the Xen BUG at
pci_amd_iommu.c:33 one I CCd you on before http://bugs.debian.org/684661

Joe, are you able to press Shift-PgUp to scroll up to the top part of
the trace? (I must confess I'm not sure that works for Xen, perhaps its
a Linux-ism).

Looks like you are already using the vga= option to increase the number
of lines displayed.

Ian.

No, once it's hung there it's stuck (doesn't even reboot in 5 seconds like it claims).

This was actually the Fedora 17 build, 4.1.3-2 and coincided with me having to remove 2 gig (bringing it down to 2 remaining gig) from an Asus K8N-DL due to memory failure. I tried rolling back to 4.1.2-15 with the same result. I found an old reference to this motherboard suggesting that with less than 3 gig, there's an iommu problem: http://www.gentoo-wiki.info/Asus_K8N-DL

I'll get this memory replaced and see if that has any effect.
