Title:
Well, I rushed last comment.
Error: (22, 'Invalid argument') still appears in LTS 4.1.2-2ubuntu2.10, but
only if I add Radeon HDA HDMI audio device.
It isn't nessessary, since Xen is adding it automatically, and then it works,
but listing it explicit in pci=['xx:xx.x'] is still causing bug to
Nope, you have to hide both from kernel. It's just, that listing 04:00.1 in
config file is causing error. At least with xm stack.
Xen is attaching it anyway runtime, so it has to be hidden or you get does not
belong to pciback error.
BTW atm im passing pci=['01:00.0','00:1a.0','04:00.0'] to the
Ubuntu 12.04.02 LTS is also affected.
Bug was introduced in:
xen-hypervisor-4.1-amd64 4.1.2-2ubuntu2.8
and still present in latest 4.1.2-2ubuntu2.9.
Downgrading to 4.1.2-2ubuntu2.7 resolves the issue.
