Before I have tried 2.6.9-1-686 (Debian unstable) and 2.6.10 (from
www.kernel.org). Now I patched the 2.6.10 up to 2.6.11-rc5, but it seems
to behave the same - same messages in dmesg as before, still timeout
when running hciattach (nothing in dmesg after this command)...
Also the same with the -mh4 patch (against a clean 2.6.10).

I checked what the working 2.4.29 shows in dmesg, maybe this helps
somewhat:

Inserting the card:
-----
cs: memory probe 0x0c0000-0x0fffff: excluding 0xc0000-0xcffff
0xd8000-0xfffff
ttyS01 at port 0x02f8 (irq = 11) is a 16C950/954
-----

modprobe hci_uart:
-----
BlueZ HCI UART driver ver 2.1 Copyright (C) 2000,2001 Qualcomm Inc
Written 2000,2001 by Maxim Krasnyansky <maxk@qualcomm.com>
-----

hciattach ttyS1 socket:
-----
bcsp_recv: Out-of-order packet arrived, got 1 expected 0
-----
(but the bluetooth device works despite this error)

One idea: is there an (easy) way to log what's going on on the ttyS1
device (I mean the communication between the hci_uart driver and the cf
card)? This way one could compare the logs of kernel 2.4 and 2.6 and
maybe see what's wrong...

Another question: What about the btuart_cs.ko module, what's the
difference to the hci_uart module?

Thanks in advance

Mathias
