Again, today, I pulled over syssrc for NetBSD 1.5.3_RC2 via anoncvs.

I built a GENERIC kernel, installed it, and rebooted. The box goes through
the usual BIOS messages, loads the kernel, and immediately reboots. Over and
over again. I tried to "boot -d", but that didn't change the behavior.

NetBSD 1.5.3_RC1 from 3/13/2002 works just fine.

Below is the dmesg from the RC kernel.
