Log:
Remove GEOM_GPT.
I encountered repeatable Unaligned access panics similar to:
fatal kernel trap:
trap entry = 0x4 (unaligned access fault)
cpuid = 0
faulting va = 0xfffffc0000fae1c2
opcode = 0x28
register = 0x1
pc = 0xfffffc00004d07dc
ra = 0xfffffc00004d0a1c
sp = 0xfffffe0031875bc0
curthread = 0xfffffc007da237a0
pid = 2, comm = g_event
These occur when a floppy or a CD (the 6.1R install CD will do in most
cases) is in the drive during boot. A floppy or CD inserted *after*
the system was booted did not give me this problem. Interestingly
enough booting from the 6.1-R install CD sometimes caused the crash,
sometimes it did not. When it did not panic an installation of 6.1-R
was possible without any incidents. A subsequent boot from HD with
the CD still present sometimes(...) worked fine, sometimes paniced.
Taking GEOM_GPT out of the kernel config file allows booting without
incidents. We do not need GPT on Alpha, so this is the easy way out.
