Hi Jeremy,

compilation[1] breaks with:

grep -i msi .config
CONFIG_ARCH_SUPPORTS_MSI=y
# CONFIG_PCI_MSI is not set

with msi configured it compiles...

grep -i msi .config
CONFIG_ARCH_SUPPORTS_MSI=y
CONFIG_PCI_MSI=y

may be its related, this compiled kernel is waiting forever at boot time
during "starting xen control daemon"...three finger salute stalls after
"unmounting network filesystems"...

if i add pci=nomsi system boots up and everything is fine :)
