With just buying some usb2 controllers instead of the usb3 ones, seemed to have
"fixed" my problems for the time being. :-)
There were also some more problems with XHCI, so it just hasn't matured enough.
It's only a pity (E/U/O)hci controllers under linux don't support MSI
interrupts, Greg KH seems to have reject a patch for that.
But apart from that it works fine ! (with the 2.6.37-rc1 kernel as domU but i
don't use NFS) :-)
So apart from some other things i'm quite happy :-)
