Hi Doug and Wilko,

Thanks for your reply. I was convinced that it was a hardware problem, too.. I installed another OS on that same machine.. just to
make sure it was a hardware problem.. big surprise! it worked
without a problem.. ..went back to FreeBSD and the problem
is again there..

Do you believe that even after that it could still be a hardware
problem? or a mix of hardware bug and software bug? May it be that
FreeBSD software uses some buggy hardware features that the other
OS just don't use?
