Hi all,

So I got my USR 2410 wifi card working in linux 2.5.59 today with 
hostap_cs. Works great! But whenever I start X i get all of this junk 
over and over and over and over on dmesg and all of my TTYs..

bad: scheduling while atomic!

Same thing every single time. It's not affecting functionality in any 
way though, so that's good :)

I shut down X and everything is peachy.

This is CVS source as of 2 Feb 2003 at about 1900 GMT-8. My kernel is 
2.5.59-mm7. I use accelerated 'radeon' X server that feeds from DRI 
support within the kernel, which could maybe be the problem?
