Nope, you found a typo in the comparison. Annoyingly, not in the i686
version, which is what I'd tested by hand before.
I've pushed an update to my x86-next branch, and updated the eflags3
branch against which I posted patches for review this afternoon.
I cloned a fresh repo, and compiled it exactly like yesterday on the
same system (I used bash's history list):
[srcpath]/configure && make -j8
Now my disk image fails to boot.
"No bootable device. Retrying in 60 seconds."
My boot command is (and was):
qemu-system-x86_64 -m 512 -cpu Haswell,+adx \
-net nic,macaddr=52:54:00:f2:81:c7,model=e1000 -net tap \
-cdrom /u/FreeBSD/FreeBSD-9.1-RELEASE-amd64-dvd1.iso -boot c -hda disk.img
I went back to the old qemu-system-x86_64 and that still works, so I
don't think the disk.img file is corrupt.
I then tried something that you might consider more plain:
qemu-system-x86_64 -m 512 -cpu Haswell,+adx \
-net nic,macaddr=52:54:00:f2:18:b7,model=e1000 -net tap \
-cdrom /u/GNU/Debian/debian-6.0.6-amd64-netinst.iso -boot d --hda disk.img
It fails similarly. (Here disk.img is pristine from a "qemu-img create"
command, but I am attemtping to boot from the iso img.)
