I am not sure if your idea has something to do with my (and some other
users) problem. So excuse me, if this posting is wrong.
For some month now I am only able to boot CURRENT under amd64 with
setting hw.pci.mcfg=0. Under i386 all works fine. Below I listed output
under i386 and under amd64. Perhaps you are able to get a hint?
Tell me if I can help in any way.
Thanks in advance,
