Cisco Aironet 340 WLAN PCMCIA 

Software Environment:
Debian unstable, kernel 2.6.10, pcmcia-cs 3.2.5
Problem Description:

When system boots with airo card or if card is inserted later
the kernel immediately freezes. No hint when plugging in the card
into the running machine, kernel is dead immediately.

When booting the famous last words are:

cardmgr[1835]: starting, version is 3.2.5
cs: memory probe 0x0c0000-0x0fffff: excluding 0xc0000-0xcffff 0xf0000-0xfffff
cardmgr[1835]: socket 0: Aironet PC4800
cardmgr[1835]: executing: 'modprobe airo_cs'
airo: Probing for PCI adapters
airo: Finished probing for PCI adapters

And that's it.

When trying this several times I once saw that the kernel 
was complaining about an unexpected NMI and telling me, that 
I probably have a hardware problem with my memory (memory works
well under 2.4)

The system works under 2.4.26 (while the airo driver had a little 
bug which sometimes lowers the bandwidht, that's why I wanted to 
upgrade to 2.6). When booting the 2.4.26, it says

cs: IO port probe 0x0100-0x04ff: excluding 0x100-0x107 0x170-0x177 0x370-0x37f
cs: IO port probe 0x0800-0x08ff: clean.
cs: IO port probe 0x0c00-0x0cff: clean.
cs: IO port probe 0x0a00-0x0aff: clean.
cs: memory probe 0xa0000000-0xa0ffffff: clean.

which is obviously a different memory range. 

Is the memory range the problem?
