Hello all,
I was recommended by the qubes-users list to ask here about an ath5k bug.
It looks like my fedora 20 networking virtual machine (netvm) is
trying to load the ath5k driver for the qualcomm atheros ar242x wifi
module in my lenovo t400, but is choking.
Here's an excerpt from netvm dmesg:

My wild guess (not being too familiar with qubes) is that passthrough is not
working properly -- this:

...looks like a pci write to an unusual address.
What does output of lspci -vnn look like, run as root in the guest?

(Regarding running inside Qubes / Xen...)
Unfortunately the VM / PCI passthrough stuff is outside my small area of
expertise, perhaps someone else knows?

Hi All,
wondering if there are any more questions/suggestions to resolve this issue?
Thank you!
