Cannot boot sparc iso with qemu on Fedora 33

[Michael Huff <mphuff%gmail.com@localhost>]

I'm trying to boot NetBSD sparc on Fedora 33/amd64 with Qemu 5.1.0 and 
it crashes.

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:

[   1.0000050] le0: 8 receive buffers, 2 transmit buffers

halt, power off

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!
