This sound very similar to my problem. I have a mirrored boot disk on an AMD64 platform.
I performed a pkg --auto-update (can not remember the command), I believe it installed to packages. Rebooted. Grub load gives the menu boots from "Solaris-1". Gets the splash screen up and sits there for a while (I assume it times out looking for something), no disk activity. Reboots, repeats. Booted from original "OpenSolaris 2009.06" successfully. Tried updating using the update manager. Installed 2 packages. Rebooted from "Solaris-2" failed in the same way as above, tried removing the Splash screen. justs gets a cursor in the top left and eventually reboots the same. This time I tried to reboot from the original as "OpenSolaris 2009.06" and it fails in the same way. I think that this may have been because I turned on timeslider. Note: The rpool is a partition on the disk not the whole disk. Sorry to msknight, no solution from me. Geoffrey -- This message posted from opensolaris.org
