Re: Cannot boot sparc iso with qemu on Fedora 33

Hi.

I'm actually running NetBSD 8.0 sparc in qemu 5.2 on Fedora 34 host.I guess it might be related to NetBSD 9 ( or specifically 9.2). I'll try to run a NetBSD 9 and see if the problem occurs. You might want to try another NetBSD version on your side.

Just in case, I started my emulated sparc machine with this command line :

# Normal Boot
qemu-system-sparc -m 256 -drive file=/srv/disk-images/nbqc1-sparc9.img -boot h -nographic -net nic,macaddr=52:54:00:12:34:69 -net bridge,br=br0

I compiled my own iso and it crashed, so I tested it with the official
one but also got the same results. I've also tried using a dump of the
OpenBoot rom (ss5.bin) and gotten the same result.

This is the command line I used:

  qemu-system-sparc -drive file=wd0.vdi,if=scsi,bus=0,unit=0,media=disk
-drive
file=NetBSD-9.2-sparc.iso,format=raw,if=scsi,bus=0,unit=2,media=cdrom,readonly=on
-boot d -nographic

It starts to boot and then crashes with the following output:

I'm not sure what else to try. I tried on an iso I compiled of
9.1-stable and also got the same results. Maybe it's qemu 5.1, or maybe
it's fedora?

I'd appreciate any insight you can give me -thanks!
