Hello,
Referring to my previous message:
https://lists.adelielinux.org/hyperkitty/list/adelie-devel(a)lists.adelielinux.org/thread/CNWIYZCFN7XDBSDCZDVIUE3SXE2EX6YF/
(still not subscribed so please cc replies to me, although there weren't
any for previous message either)
I've tested beta3 with latest QEMU on x86_64 with TCG (you mention testing
on PPC hardware with KVM in the beta3 release notes but I don't have PPC
host so I use TCG). The exception is still there by just booting the
livecd iso but now pressing c then linux /bzImage; initrd /initrd; boot
from grub> prompt is enough to avoid it. However then it hangs after Linux
kernel is started. With my patched openbios-qemu.elf the exception does
not happen with beta3 and starts from menu but the hang is the same after
that. I still can only boot beta2 with my patched openbios version as
described in previous message so it's not related to QEMU changes but I
think it depends on how things are laid out in memory. Is there anything
else I should know about running Adelie Linux on QEMU?
I can get some more logs if I run it as:
qemu-system-ppc -M mac99,via=pmu -m 1024 \
-boot d -cdrom adelie-live-ppc-1.0-beta3.iso \
-d unimp,guest_errors -nographic -serial stdio -monitor null
still need to go to grub> prompt and do linux initrd boot, then I get:

After this I see it's poking PCI BARs then nothing else happens.
That's all I could find out, any idea how to debug this further?
(As this may be OpenBIOS related also cc-ing OpenBIOS maintainer.)
