When you run it --no-upload option, you'll get the file on your local
machine.  Anyway, I don't see why Jens' patch breaks your machine.
The PCI SSID (not codec SSID) of his machine is 17aa:215e while yours
is 17aa:20f2.  The breakage can be a coincidence.

Could you check whether model=thinkpad works better?
If yes, we can simply add the new entry for your device.


thanks,

Takashi
