well.. i think this is really something to escalate now since there is
obviously a problem. today again i tried a little bit and as told, the
isntance B crashes the system reproducible. In my opinion something like
this should really be examined further, since a userspace program
shouldn't kill the hole system...
for me this really looks like several people have similar problems but
so far there's no investigation since nobody knows what the actual problem.
any ideas how to proceed? can i provide any additional information?
since the system reboots immediately it's hard to investigate the
process of crashing itself.. at least for me.
