Offlist question: Hardware problem with ultra2

[Georg Chini <georg.chini@triaton-webhosting.com>]

Hello,

I have an ultra2 machine with a hardware
problem. It runs through POST without errors
and everything seems fine, but it stops soon
after the selftest sequence.
Here are the last things I see:
....
0>CPU Functional Test
0>    Mapping Selftest Enabling MMUs
0>    SPARC Atomic Instructions Test
0>    CPU Dispatch Control Register Test
0>    CPU Softint Registers and Interrupts Test
0>    CPU Tick and Tick Compare Registers Test
0>    Uni-Processor Cache Coherence Test
0>    UltraSPARC-2 Prefetch Instructions Test
0>              *UltraSparc-1 module detected, tests skipped
0>
     << POST COMPLETE >>

Any ideas what might cause this or how to solve the problem?
Thanks a lot in advance.
