Debian Jessie regression under qemu-system-sparc64
Hi all,
As part of the QEMU 2.2 release process, I've been testing various Linux
images to make sure that there are no regressions under
qemu-system-sparc64. However it looks as if in recent days something has
badly broken:
$ ./qemu-system-sparc64 -cdrom
/home/build/src/qemu/image/sparc64/mini.iso -boot d -nographic

It looks like the regression has been introduced sometime between
4th-8th November:
- Works, boots to the Debian installer
http://d-i.debian.org/daily-images/sparc/20141104-00:20/mini.iso
- Doesn't work, crashes as above
http://d-i.debian.org/daily-images/sparc/20141108-00:22/mini.iso
Does any know what has changed that could have caused this regression?
Kind regards,
Mark.
