Are you using this same vmlinuz-chrp.initrd?
$ md5sum vmlinuz-chrp.initrd
a440d76c1d2ccfa86bdff6dba017cf39 vmlinuz-chrp.initrd
Yes, md5sum is same as you mentioned:
yogi@fedora:~/work/images$ md5sum vmlinuz-chrp.initrd
a440d76c1d2ccfa86bdff6dba017cf39 vmlinuz-chrp.initrd
Could you please share your Qemu configure command line?
I can try one more time if that's different than mine.
I used below configure command line:
'../configure' '--target-list=ppc64-softmmu,ppc-softmmu' '--enable-virtfs'
I don't see how configure options could have anyhing to do with that but
I've tested that this works on my machine:
configure --disable-download --disable-tools --target-list=ppc64-softmmu
qemu-system-ppc64 -M pegasos2 -serial stdio -kernel vmlinuz-chrp.initrd
-append "---" -cdrom debian-8.11.0-powerpc-netinst.iso
The configure options are just to only compile what's needed but it should
work anyway with your or any options too as long as qemu-system-ppc or
qemu-system-ppc64 is compiled. Can you test on a different machine?
Someone else reported a possible regression maybe related to this patch too
Debugging with the other person reporting similar issue I think I've found
the problem and this patch should fix it:
https://patchew.org/QEMU/[email protected]/
Can you test please?
