Howdy. Since somewhere around the .22-pre7 (or -pre6) area wlan-ng
stopped working. I've tried the wlan-ng-2.4.1-pre1[01] drivers with
various pristine and -ac kernels since .22-pre8 and

The file oops.txt is generated when trying to load prism2_cs in a
2.4.22-rc2-ac3 kernel; the file oopsout.txt is from 2.4.22-rc2. Both are
trying to load the wlan-ng 2.4.1-pre11 driver. It looks like a problem
within prism2_cs.. but the drivers work with 2.4.21* so my ignorant guts
tell me it's more likely pcmcia has changed somehow to affect this.

Let me know if anyone requires further info. I'll do what I can.
