Phenoms and recent OpenSolaris developer builds

I’ve just tried to update my desktop to the newest developer release for the upcoming OpenSolaris 2010.2. But the system just fscked up right after the boot. This error was introduced somewhere after build 111a of Opensolaris. The bug looks strange as you just see the splash screen, press a key and the system reboots. But when you modify the grub commands to enforce a text mode boot, you will see a message reporting an unexpected trap. I think it’s this bug described at with the bug id 6844241. The fix is commited for build 126.
