Hi
I've tried the proposed flags - I got some additional dmesg:
6.000171] Kernel command line: root=ZFS=warehouse/gentoo dozfs=force
intel_iommu=on pcie_aspm=off pcie_ports=compat
xen-pciback.hide=(00:1b.0)(02:00.0)(03:00.0)(03:00.1)
[ 6.370424] pciback 0000:03:00.0: no compatible bridge window for
[mem 0xfff80000-0xffffffff pref]
[ 6.370481] pci 0000:04:00.0: no compatible bridge window for [mem
0xfff80000-0xffffffff pref]
[ 6.370538] pci 0000:05:00.0: no compatible bridge window for [mem
0xfff80000-0
...
[ 6.000235] PCIe ASPM is disabled
However that didnt truly help out.
I might wonder if this has something to do with the fact that Im not
able to enable interrupt remapping.
Thus I also have pci_msitranslate = 0 - if I put it on 1, I get wired
distortions in the DomU (with stdvga).
Up to now, I thought that I do not really need interrupt remapping...
maybe this has also something to do with the 'err code 43' while running
Xen 4.3.x?
regards,
Georg
PS: xl dmesg output below.
