Haven't tried rebooting a lot of times without iommu yet. (the reason i bought the 890fx board in the first place) Will try that a few times when i have some more time. -- Sander Wednesday, October 19, 2011, 6:38:38 PM, you wrote: > It looks similar.=20 > Hi Sander, could you please test your system with the following options? > 1. iommu=3Damd-iommu-perdev-intremap in xen.gz GRUB entry > 2. pci=3Dnosmi in pvops GRUB entry > 3. iommu=3D0 in xen.gz GRUB entry [optional, only if (1) doesn't work for= you] > We were seeing an issue which was caused by messed-up interrupt remap tab= le.
