ah, thanks for your research.

this time it's gotten nasty:

possibly there is some kernel switch which could be used to disable 
usage of "ORDERED queue"
everything seems to work, but possibly it can get still worse.
i guess it's better to disable it until qemu supports it...

i'm actually glad that aboriginal comes with the comfortable qemu start 
environment,
so that i don't have to mess around with qemu myself... (yet another 
tool to master)
