Yesterday the freze 
also happend in a non SMP CAM-19980712 Environment (same kernel 
without SMP as before). The only stable System at the moment is 
the 2.2.7-RELEASE. I never get a freeze there.

So lets conclude: There seems to be a Problem in 3.0-SNAP SMP, or/and 
                  3.0CAM SMP and nonSMP which lead to an abrupt 
                  freeze of the system.
		  It can't be a hardware problem, cause 2.2.7 is rock stable
		  on the same machine!

Any ideas how I can help to find the error?

Best regards

Lars

PS: I'm on holiday until 17.9.
