I just tried the newest CVS and still got the same results. Here's a copy of the offending oops and the output from ksymoops.

Please note that I'm using pcmcia-cs 3.2.1 source/drivers on a DEC Alpha instead of the native kernel drivers. I couldn't get the hostap driver to compile when I use the kernel source.
