is this what you mean by 'hosed'?

I haven't run across this term before :-)

you make me shiver!
this is an almost brand new machine (purchased only a month ago)
and except for the java zombies and a loss of acpi events after suspend that
happened with an older kernel but noch anymore with this one I don't
experience errors that make me think of hardware defects

what does it try to tell me?

ok...
I will go and bake a naked kernel now, but please give me some hints, what
makes you think it is THAT bad?
I am computer scientist myself but not a hardware nor a kernel hacker.
So I guess I will understand what you tell me even if I am probably not able
to fix it myself

thank you
