[Xen-devel] XEN 4.3.4/4.4.3 Dom0 reboot loop with AMD FX-8350/Gigabyte GA-970A-UD3]

["NiX" <nix@xxxxxxxxxxxxxxxx>]

Hi. As the subject says. Where from I do start debugging it? My kernel
boots fine on that machine without XEN.

I tried the following command line option:
noreboot=true,iommu=1,no-amd-iommu-perdev-intremap

OK that stop the loop but how do I get the output so I could see the cause
of crash/restart? Screen goes just blank with noreboot=true

I do have AMD-Vi/IOMMU enabled in the BIOS. Tried both F1/F2g BIOS but
reboot loop still exists.

Both XEN's are compiled from source via GIT repo.

My kernel is 3.2.68 with grsec. Disabling grsec made now difference.

I've attached kern.log. Here's lspci output:
