Yep, same here with a HP dv6361 notebook. However, the following *may* help...
It would appear like Solaris automatically boots a kernel that matches the architecture of your CPU (i.e. 64-bit or 32-bit). But you can force OpenSolaris into 32-bit if you want. When the CD boots into Grub, press 'e' and then press 'e' again on the line that starts with 'kernel'. Delete '$ISADIR/' -- This will have Solaris boot the 32-bit kernel. Scroll to the end of the line, append a space, then add '-B acpi-user-options=0x8' Press Enter Press 'b' to boot. If this still doesn't work, replace '8' by '4' or eventually by '2'. For further information, please see here: http://blogs.sun.com/danasblog/entry/configuring_solaris_acpi_at_boot Unfortunately the above still fails to boot OpenSolaris on my notebook. Interestingly enough, the proprietary Sun edition of Solaris does boot on my system if I make the changes above! The Sun Solaris build I tested with is 103, whereas OpenSolaris 2008.11 is build 101b. -- This message posted from opensolaris.org
