No worries. As I said, this was purely informational. Ever since 6.18
Linux started to break on more and more platforms in my tests. I can not
keep up with testing or analyzing the problems, so as I find issues I
report it and stop testing if the problem persists over a couple of
releases. As in this case, it is obvious that no either one cares, that
it is a problem with qemu, or a problem with my setup. Given all that,
even if the problem is not related to my setup, it would be a waste of time
trying to track it down or to keep testing.

Thanks,
Guenter
