Subject: BUG: scheduling while atomic: events/0/0x00000001/10

Hi Ingo,
   I brought up the -rt kernel on my son's SIS-based machine and got
this bug report in dmesg this morning. I've not seen this on previous
standard kernels so I thought I might be of interest to you. Let me
know what other sort of info you might want to have (if any) and I'll
post it along.

   He has run other MUCH older -rt kernels, circa 2.6.9 or so. I'm
assuming this is new because of the rt_mutex stuff.

   Networking is working since I'm writing this email on the same machine.

Cheers,
Mark
