I'll try that. But I know for sure that the machine is still pingable
after a crash.
With 5/20/60 minutes I want to say, that it doesn't seem to happen every
time after 5 minutes. And it always happens when I am doing something.
It would be an interesting test to let the laptop run the whole night,
but I am afraid to do that, because I read that my laptop will burn when
ACPI is not working properly and I learned that there is no out of the
box ACPI and I would need to learn how to patch a kernel etc. first.

I do get pings though.

Ok, I will try that.

Ok, I will try that.

Thanks very much for your help and encouragement.
