Subject2.5 kernel + hostap_cs + X11 = scheduling while atomic
Hi Jouni and LKML folks,

In kernel 2.5.59 I built the hostap modules as stated in the Makefile.
(make -C /usr/src/linux SUBDIRS=$PWD/driver/modules modules, etc.)

However, a combination of running said kernel, hostap_cs, and X11 produces
this nasty infinite string of errors:

bad: scheduling while atomic!
Call Trace:

This will repeat itself over and over again in the same order, same everything.
The second I kill X the messages stop completely. I use the radeon accelerated X
server using an Intel AGP bridge (kernel supported.)

Any ideas? It seems like it would be a problem in hostap_cs's main loop. Or it
could be a kernel problem, which is why I'm forwarding it to LKML :) Why would
it only happen when X11 is active though?

Thanks for any insight anyone might have on this issue. Lately, I left my machine
on and went to go eat lunch. When i came back, /var/log/syslog was overflowing with
these errors and had filled up /var completely. Had to purge them all manually :)

Regards

Josh
