Re: CPU panic on Ultra 10 - RESOLUTION!

Hello!

OK - thanks to the overwhelming response I got from everyone - I was
amazed! I have managed to sort the problem now - I have removed one of
the hard disks which apparently seems to be faulty (as far as the SPARC
machine thinks, anyway... I have tested the hard disk on an intel
machine running linux and it came back fine without any problems, so I'm
gonna just use it there instead...!) and that was what was causing my
CPU to panic on boot. System is now fully up and working, and running
Solaris 9. Superb stuff!
