Hello!
With r37237, I built malta and x86 target with default configuration. But they
both failed to boot up on qemu of version 1.5.1, i.e. there is no shell prompt
and virtual machine just hangs and eats up CPU.
I guess procd is the culprit. With malta, the bootlog shows no sign of
procd, yet it is supposed to be run as init.

With combined i386 image, it booted and procd run as init, but no shell prompt
showed up. Failsafe mode worked fine.
From grub2 menu, I added additional kernel paramter "init_debug=9" to let procd
print more information.

I'd like to help pinpoint the bug position, but that there are so many image
names (initramfs, combined, rootfs) confuses me.
BTW, Malta target is not built for attitude adjustment [1]. Malta for
AA-12.09-beta2 works fine for me on qemu.
Directory `target/linux/malta/patches-3.6/` is empty and not needed now.
