Hmmm not necessarily. It seems that the Darwin crash only manifests itself on -M g3beige (the default) rather than -M mac99, although I can confirm that HelenOS crashes on both -M g3beige and -M mac99: ./qemu-system-ppc -cdrom HelenOS-0.6.0-ppc32.iso -boot d -bios -m 256 -M mac99 >> My only request is if it would be possible to move patch 2 "ppc: Better >> figure out if processor has HV mode" to the front of this patchset which >> will make the remaining patches bisectable for the Mac machines.
