Title:
[qemu-ppc] Segfault when booting from HD after MacOS9 install
Status in QEMU:
Expired
Bug description:
I created an empty 128G qcow2 image and booted from a Mac OS 9.2.1
Install CD, in which I was able to install the OS successfully to the
hard drive. Upon reboot, this time from the hard drive directly, qemu-
system-ppc segfaults. Host system is Ubuntu 16.04.2 with latest qemu
commit.
qemu --version reports "2.10.50 (v2.10.0-244-gb07d1c2-dirty)", but I
used git commit b07d1c2f5607489d4d4a6a65ce36a3e896ac065e and built
with "./configure --target-list=ppc-softmmu --enable-debug --disable-
strip".
Here is the command-line arguments:
qemu-system-ppc -boot c -g 1024x768x32 -M mac99 -m 256 -prom-env
'auto-boot?=true' -prom-env 'boot-args=-v' -prom-env 'vga-ndrv?=true'
-drive file=../os9.img,format=raw,media=cdrom -drive
file=MacOS9.qcow2,format=qcow2,media=disk -spice
port=5901,password=XXX -net nic,model=rtl8139 -net user -monitor stdio
And the GDB backtrace:
Program terminated with signal SIGSEGV, Segmentation fault.
