Re: Issues with NetBSD 8.1 macppc

Hi,
It seems I was a little too enthusiastic about NetBSD 8.0/8.1 and my Ibook
G4. The install "kernel" doest work. It boots. I can install NetBSD fine
but as soon as I boot to the generic Kernel it crashes with a Kernel Panic.

I mostly followed this guide for the installation :
https://wiki.netbsd.org/tutorials/how_to_install_netbsd_on_a_power_macintosh_g4___40__grey__41__/
Only diffrences were :
- Booted on usb flash drive ( CD/DVD drive has a screw through it )
- Partition goes that way :

   1: Apple partition map
   2: 32m HFS boot
   3: 2g Apple_UNIX_SVR2 swap      b
   4: 35g Apple_UNIX_SVR2 /              a

-  Did not install hfsutil from pkgsrc but from pkgin instead
- I read somewhere that having Kernel with ofwboot on HFS partition is a
good Idea. So I copied the Kernel on the 32m HFS partition.

As soon as I try to boot from HD ( boot hd:2,ofwboot.xcf netbsd or boot
hd:2,ofwboot.xcf hd:4,/netbsd) i got these messages : --db-more-trap Kernel
ISI by 0xff8472b0 (SRR 1 0x40003030), 1r: 0x1001e4
Skipping crash dump on recursive panic

These look like the one I got with qemu.
I did some digging and I foud this (
http://mail-index.netbsd.org/port-macppc/2019/06/02/msg002583.html)

So I basically copied the ofwboot.elf in my HFS partition and tried to boot
with " hd:2,ofwboot.xcf netbsd" and VOILA ! It boots now !
I also tried to boot with the Kernel on the FFS partition and it works too.

I was wondering if this could fix the problem with NetBSD 8.1 and
qemu-system-ppc however ofwboot.elf is not on the iso. Do you think it
might be possible to add it ?
