seemed that I'm getting Kerneloops trying loading rtdm drivers:
This is what I see while trying to load the timerbench driver.

This really confuses me, especially I compiled now the Kernel with a config file
out of my archvie which worked fine with 2.6.15 and ipipe-1.2*, Anybody an Idea for this?
Thanx again
cheers
