Title:
qemu-system-ppc segfaults when booting from Debian lenny netinst image
Status in QEMU:
Fix Released
Bug description:
I get a segfault from qemu-system-ppc when booting from the Debian
lenny netinst image. I'm using QEMU 0.12.3. The host machine (on which
QEMU was compiled) is:
[iansealy@zebra]~$ uname -a
Linux zebra 2.6.31-20-generic #57-Ubuntu SMP Mon Feb 8 09:02:26 UTC 2010 x86_64 GNU/Linux
A gdb trace is below. Any other info I can provide?
[iansealy@zebra]~$ gdb --args ~/packages/qemu/bin/qemu-system-ppc -hda debian-lenny-powerpc.img -cdrom debian-504-powerpc-netinst.iso -boot d
