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 ?

Hi,
I tried to boot without "via=pmu" option. Still Kernel panic on boot.
The message "oea_startup: failed to allocate DEAD ZONE: error=12" does shows up when booting on NetBSD 8.0 but it does not seems to affect the booting process.

Another point : I tried to boot with NetBSD 8.0 and 8.1 on my ibook g4. Both seems to work fine with real hardware.

I haven't been following NetBSD development too closely, however the "oea_startup:
failed to allocate DEAD ZONE: error=12" message looks slightly suspicious - does that
appear when booting 8.0 in the same way? And are you able to boot if you remove the
"via=pmu" machine option?

ATB,

Mark.
