I recently got a v215 from a friend and have installed OpenBSD on it. Occassionally, it will panic during boot. This happened during install and I see it now during regular reboots. I can pretty much reproduce this at will with a couple of reboots.
Could this be faulty hardware ? To reset the ALOM password, I installed Solaris 10 (took an eternity) and that never showed any problems, but I guess that doesn't prove much. First the panic and then full dmesg (from a succesful boot) are included below.
