AW: Re: [Xen-devel] Re: PCI passthrough stopped working, brainache!



Interesting. Konrad, do you remember that one of my DVB cards did 
consume double CPU time 
as compared to a) old Xenified 2.6.18 b) Xenified 2.6.34 and c) mem=2G 
Dom0? Maybe these
observations are somehow connected.

It did work, though... Unfortunately, I sold these cards to have only 
one, which is 

Carsten.

A coconut for the gentleman!

Working in dom0 and (with page-alignment of the PCI BARs) in the domU,
I did check a couple of reboots and a cold start too, just in case!

So what's to look at for the real cause?
