It sounds like you are running into a bug in Solaris or, more likely, a failure on Solaris' part to work around a bug in your BIOS. To get more verbose messages at boot time, Press "e" while at the GRUB boot menu, then "e" again to edit the command line of the boot command. The add the following to the end:
-v -m verbose and then press enter to boot Solaris. You should see Solaris log a lot more messages to your screen. Post the last few lines of this output here. Cheers Andrew. This message posted from opensolaris.org
