SubjectRe: 2.2.0-pre7ac2 PCI probing fails
Hello,

> As I have previously reported, probing the PCI bus with direct access

> Bus 0, device 21, function 0:

> Vendor id=4978. Device id=84c5.
> Fast devsel. IRQ 19.
> I/O at 0x0.
> Non-prefetchable 32 bit memory at 0x90100.

Please send me all PCI-related boot messages when booting with direct
access and output of 'lspci -vvx'.

Have a nice fortnight
