pccard CIS reading problems

[Stuart Walsh]

Hi folks,

There has been one or two mentions of the atmel chipset wireless cards
on this list before, but nothing much said, so I decided I would try and
port the linux driver, or at least attempt to.

Using a fresh checkout of -current, when you insert the card it causes a
page fault which I tracked down to a runaway loop in pccard_scan_cis.  I
added the sanity check that NetBSD has in this function and that stopped
the panic.  However, the CIS info that is being read is obviosuly
garbage and mostly zeros.  This leads me to believe that the card's
attribute memory isnt being mapped properly or something.  This thing
is, under NetBSD, the pcmcia driver _can_ read the CIS, and it comes up
with the proper info.

Can anyone shed any light on this or point me in a direction to go from
here?

Thanks,

Stuart
