I've now removed this driver from my .config via menuconfig, I certainly don't
have the hardware and have no idea whatsoever how it came to be built in.
Although I guess it shouldn't be blowing up even if that is the case?

lspci -vv shows that when the driver fails we see this:
Status: Cap+ 66MHz- UDF- FastB2B- ParErr- DEVSEL=fast >TAbort- <TAbort- <MAbort-
>SERR+ <PERR-
and when it works we see this:
Status: Cap+ 66MHz- UDF- FastB2B- ParErr- DEVSEL=fast >TAbort- <TAbort- <MAbort-
>SERR- <PERR-
I'm not sure if that's a consequence of the fail, or the cause of it.

I reloaded multiple times, the oopsing only occurred till I did a full cold
boot, and then it came right (but until then I had the oops twice in a row
across a warm reboot).
If I have time to play later on today I'll see if I can get more info.
