How are you trying to 'break' it? Through a serial console? If so, how is it connected? What kind of terminal or emulator are you using?

If you're not going through the serial port, it's probably because your keyboard isn't being detected (see the "No Keyboard" message). Annihilannic.

I've had trouble sometimes when trying to break via the serial port. You can patch Solaris to ignore breaks (because some terminal servers send breaks when they are rebooted, like Cisco). Try hook up a Sun keyboard and monitor directly and break it via the Sun hardware.

If you can get to the firmware prompt see if you can boot from a CD-ROM. That will tell you if your panic is due to something on disk or if you have a hardware problem (CPU/memory).

I am brand new to this group and realize this thread is a couple months old but replying in the event somebody has a similar issue in the future.

The Sunfire v100 has a LOM( lights out managment...serial) port and no keyboard or monitor. To break out of this loop you must connect to one of the 2 ports. Connect up using hyperterminal or similar terminal program. Once you have connected type "#." that will send you to the LOM functions. Here is where you can control this...the break is issued by typing "break". You can type "help" for a list of the commands that are available. Hope this is helpful to somebody.

v/r,
