hostap-0_6_6-148-g3cf8523 ie git build from ~ dec 24.

It can, but i'd like to try to get hostap running w/ this hw anyway...

yes, but only after patching hostapd; the lockups prevented further
testing...

I'll send it in a few minutes, as soon as i'll reproduce it.

most of the times it happened there was no kbd attached. At least once
when it _was_ connected, sysrq was working, and i saw 0*8KB; that's why
i initially suspected fragmentation.

I'll consider setting up another similar machine for testing, so that i'll
be able to run w/ more debugging enabled. I was hoping to avoid it, esp.
as i'm not sure i'll be able to reproduce the problems w/o the load.

thanks,
