Could you try with this patch, it should fix the "scheduling while
atomic" error in airo.c.
It actually also includes a few other things, mostly cleanups and fixes
pulled from the CVS version of the airo.c driver for 2.4 so I don't
think it will cause you any harm. It has worked well for me on three
fairly different cards, (a PCMCIA, a PCI card, and a Mini-PCI).
Later,
Tom
