Dmesg when booting with docking station
Vaio Z21 has a docking station, connected to the notebook using
Thunderbold/Light Peak, which is, as far as i understand, it just PCIe. It
contains a USB hub, a graphic card (Radeon), and I can see a network and a
sound port. When booting with the docking station attacked, everything except
for the graphic card works (see all the logs *_dock). When I then unplug it
(see all the logs *_dock_undock) and replug it (see all the logs
*_dock_undock_redock), nothing from the docking station works anymore, except
for the power. When booting without it plugged in (see all logs *_nodock) and
then plug it in (see all logs *_nodock_dock) nothing works except power.
This bug is not about the graphic card not working. I thing I'll make a
different bug for that, since I don't think it is connected.
I will append the output of dmesg, lspci, and lspci -t for all situations.
Notice that the pci-devices are not detected in the situations where things
don't work.
