Hi Jan / Konrad,

Tried bisecting, but that ended up no where, so back to the logs...

With v3.9-rc0 + xen, it's indeed missing a part of the log:

The line in the serial-log also seems to be truncated somehow and the rest of 
the info missing ..

When booting v3.9-rc0 Baremetal the complete pci enumeration seems to be in 
between:

Tried booting with pci=nommconf,nocrs but to no avail.
Are there any other boot options i could try to narrow it down ?
