Hello.

I just did some more testing too..

I upgraded to the latest patches for Linux 2.6.29-rc1-tip

log of xen+kernel from serial console:
http://pasik.reaktio.net/xen/pv_ops-dom0-debug/pv_ops-dom0-bootlog-5-xen331-linux-2.6.29-rc1.txt

(XEN) Command line: dom0_mem=1024M loglvl=all guest_loglvl=all com1=19200,8n1 
console=com1
Kernel command line: ro root=/dev/vg00/lv01 console=hvc0 earlyprintk=xen 
pci=nomsi

And the failing part of the log is here:

xen_allocate_pirq: returning irq 30 for gsi 18
xen_set_ioapic_routing: irq 30 gsi 18 vector 160 ioapic 0 pin 18 triggering 0

xen: PCI device 0000:00:1f.1 pin 1 -> irq 30
