For some reason the kernel is deciding that your machine is not PCI-capable. *grmbl* i really did not notice that %-} Rather unhelpfully, the kernel can print that message in three different places. The files concerned are: linux-2.6.8.1-xen0/arch/xen/i386/pci/irq.c linux-2.6.8.1-xen0/arch/xen/i386/pci/legacy.c linux-2.6.8.1-xen0/arch/xen/i386/pci/common.cYou may want to edit the print statements to distinguish them, so that we can see which one(s) are actually being triggered. It looks like maybe raw_pci_ops == NULL, even though that should be impossible! At the same time the kernel prints 'Using configuration type Xen' it should set raw_pci_ops to a non-NULL value.
here we go:

the full output is attached again. this time it was on a different machine with
/lib/tls still in place
but normally i ran it with thread local storage disabled. i'd like to debug
this further for/with you
if needed but i can not get back to you before october 19th.
happy hacking.... :)
