Today, I installed OpenSolaris 2008.05 on a Sun X4100, and then did "pkg refresh" and "pkg image-update", following the release notes for 2008.05. Upon reboot, I selected "opensolaris-1" from the grub menu. the machine panicked almost instantly.
I followed post number 2 and it worked! After upgrade I got snv_95 running. It is really bad that opensolaris panics even on Sun hardware after following the release notes perfectly. This message posted from opensolaris.org
