Re: NetBSD 10.0 on a Mac IIci

[Stan Johnson <userm57%yahoo.com@localhost>]

NetBSD 10.0 doesn't seem to boot on the IIci with any Nubus video card
installed, including the Macintosh II Video Card (Toby Frame Buffer).
This may be a bug, since the installation documentation says that most
basic unaccelerated Nubus video cards are supported, and an earlier
document specifically says that the Toby card is supported:

https://www.netbsd.org/ports/mac68k/info/chap-features.html#video-cards

Please let me know whether I should report this issue as a bug.

Also, there may be a memory problem with NetBSD 10.0 on the IIci. I see
this on an 80 MiB system (64 MiB in Bank A, 16 MiB in Bank B):

If I install 64 MiB in both Banks A and B, I see this:

So meminfo is showing all the memory, but dmesg is getting it wrong, and
memory usage by [system] as reported by ps seems high, perhaps
swallowing up much or all of the available memory in Bank A. That's a
guess, since I don't know much about NetBSD.

I can post the serial console logs of the kernel panics with Nubus video
cards installed if anyone is interested, or if there's a better way to
file bug reports (one for the Nubus video cards, one for the memory
issue), let me know and I'll do that.

thanks
