system reboots after insmod rtai_hal

[Daniel Rohrbach]

Hello list,

I'm, facing a strange problem: 
Everytime I insert rtai_hal.ko, my embedded system reboots after printing

Adeos: Domain RTAI registered.
RTAI[hal]: Loaded over Adeos 2.6r8c5/x86.

My system:
fusion-0.6.1  (it also reboots with 0.5 or 0.6)
Linux-2.6.8.1 patched with r6c5

Does anybody know, what could cause this problem? I don't think it is a 
problem from fusion, because it also crashes with fusion-0.5 and fusion-0.6. 


Daniel.
