Well,
Given the lack of suggestions today, I spent the evening poking around
in the PCMCIA code. I have discovered that the xe_probe routine is
apparently unable to see the CIS. It apparently maps it OK, but thanks
to some additional debug (partly enabling what was there, and partly
adding new stuff), I came up with this:
Nov 13 01:51:39 pooh pccardd[88]: Using I/O addr 0x2e8, size 8
Nov 13 01:51:39 pooh pccardd[88]: Setting config reg at offs 0xff80 to

Nov 13 01:51:44 pooh /kernel: xe0: xe: Probing
Nov 13 01:51:44 pooh /kernel: xe0: Got version string (0x15)
Nov 13 01:51:44 pooh /kernel: xe0: version string = 85 ""
Nov 13 01:51:44 pooh /kernel: xe probe result = 6
Nov 13 01:51:44 pooh /kernel: pccard2: device_probe_and_attach error 6
Nov 13 01:51:44 pooh pccardd[88]: driver allocation failed for
Xircom(CreditCard
Ethernet 10/100 + Modem 56): Device not configured
Now, the version string shouldn't look like that, and should only be 59
characters long, not the 85 reported here (the number before the string
is CISTPL_LEN(buf) ). My best guess here is that the new cardbus stuff
has somehow confused the xe driver. So, is there any way, other than
reverting to 4.3, to disable the cardbus support and revert to the old
mechanism? Sadly, my BIOS doesn't let me force a compatible mode.
Thanks in advance,
John...
