Summary : Ultra 30 panicing on thermal warning

I want to thank Francisco, Andrew, Musa, Kwanghoon and Mathew for their
prompt response.

Most replies stated that a prtdiag -v should show me some internal
temperature readings. Running this command on my Ultra-30, unfortunately
didn't show any information about temperatures what so ever. Maybe
someone knows another command that will show the temperatures inside my
Ultra-30.

Mathew said that the /var/adm/message log was a typical CPU fan
malfunction, so this is the next thing that I will be investigating over
the next few days.

Greetings,
Peter
