GENERIC 5.1.2 panics on 7248/120

[Hisanobu Tomari <htomari%myopera.com@localhost>]

Hello,

I recently got an IBM 7248/120 computer and was happy to find NetBSD
support it. NetBSD was successfully installed on the machine using
network booting. However the GENERIC kernel panics during boot.

I'll try building custom kernel on another machine, and I'd like to know
if there are suggestions on what options to turn on/off.

Thanks in advance.

Here's the console output:
