2.6.15-rc2-mm1: kernel BUG at kernel/timer.c:213

[Bernhard Rosenkraenzer <bero@arklinux.org>]

This happens when modprobe-ing rt2500 (http://rt2400.sf.net/) -- since the 
same driver works perfectly on older kernels, the timer rework may be at 
fault (didn't have a lot of time to look into this yet)
