[Xen-users] Lots of IOAPIC or GSI related errors

[Sven Köhler <sven.koehler@xxxxxxxxx>]

Hi,

I'm getting lots of IOAPIC and GSI related errors, both in xen's and the
dom0 kernel's dmesg (see below).

It might have to do with the fact, that I added "acpi=ht" to my xen
command line. Previously to adding that, the errors didn't show up. But
I added it, because it was said to fix my reboot problems. But along
with adding acpi=ht, I also upgraded dom0 to kernel 3.7.1. I'm using Xen
4.2.

My grub settings are as follows:
kernel /boot/xen.gz dom0_mem=512M acpi=ht vga=mode-0x314
module /boot/vmlinuz root=/dev/md0 ro quiet


Regards,
  Sven
