Re: NetBSD 10.0_RC1 on AlphaServer DS25... no boot




A friend and I were working on an ES40 last night and hit a similar failure. I'll check with him today and see what the panic was.

Hi, all,

I've finally gotten my AlphaServer DS25 to the east coast and finally have it set up to run :)

The first thing I want to do is to update it to NetBSD 10.0_RC1, since the last upgrade was almost exactly a year ago. I built a GENERIC kernel from today's (30-Dec-2023) sources, then tried to boot it:

Boot file: netbsd.old
