 I tested the actual kernel source from CVS. The problem occurs again in a 
 slightly different way. Some minutes after booting the kernel goes into an 
 endless loop (no response to keyboard and no response to pings).
 
 I tested it on different DELL 1850 Systems, so I am sure that the problem 
 is no hardware failure.
 
 I can enter the ddb. bt shows the following (one example):

 If needed, I can also create a kernel dump.
