Computer booting to xen0 hangs if I don't disable ACPI (computer has two Xeon
processors). Even "acpi=ht" doesn't work.
The last lines displayed are many messages like:
...
PCI: BRIDGE ...
IO window: disabled
MEM window: disabled
PREFETCH window: disabled
...
and before that two lines with something like:
PCI: Cannot allocate resource region 4 of device ...
With ACPI disabled it boots normally:
/boot/grub/menu.lst:
...
title Fedora Core (2.6.16-1.2080_FC5xen0)
root (hd0,0)
kernel /xen.gz-2.6.16-1.2080_FC5 acpi=off
module /vmlinuz-2.6.16-1.2080_FC5xen0 ro root=/dev/VolGroup00/LogVol00
module /initrd-2.6.16-1.2080_FC5xen0.img
...
Is there anything I can do to get hyper-threading working?
