Most recent kernel where this bug did *NOT* occur: none
Distribution: Debian unstable
Hardware Environment: EPIA MII 12000
Problem Description:

Several problems occur with the PCMCIA bridge on this board. I would first get the 
cs: pcmcia_socket0: unable to apply power.
message each time i would plug in a card. The message went away when adding the
override_bios=1 option to the yenta module.

Now however I am seeing an even stranger behavior. When I plug a PC-Card WLAN
adaptor, which is known to work on my laptop, the card reports a wrong value as
its device identifier:

The card's description as seen on my laptop is:

Note the one bit difference in the device ID (0102 / 0302). The memory area
seems to be borked too.

I have tried adding pci=assign-busses but with no success.

The controller is the RL5c476 II (rev 80) which I have read has numerous problems.
