No go meant no changes. If I had a new info, I'd show it. ;-)

The trace was the same and I suspected that I've done something
wrong. BTW, while driving home I realized that I had built and
installed the wrong kernel (the kernel for i386 diskless booting,
with which I used to work the whole day). Well, it was a hard day.

And finally you are a winner! After building and installing the
kernel for the host machine the trouble went away. Yay! Kostik,
great work, thanks!
