It is strange, but there's a way to confirm it is gcc: with your world built without setting CPUTYPE (as you have it now), compile and install *JUST* the loader with CPUTYPE defined. The steps to do this (the 'grep' just shows that CPUTYPE is set): # grep CPUTYPE /etc/make.conf CPUTYPE?=p-m # cd /usr/src/sys/boot/ # make depend && make && make install && make clean && make cleandepend When I tried the same thing on my athlon-xp machine, the new loader worked. So it is only when gcc is compiled with CPUTYPE set that there is a problem. I now run 5.4 on the machine and no longer experience the issue, so who knows... -- Jonathan Noack | noackjr@alumni.rice.edu | OpenPGP: 0x991D8195 --------------enigA10F4A360495E42255A9D604 Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.1 (MingW32) iD8DBQFCi3f+UFz01pkdgZURAqp4AKDgCa4NHlJXJFvNsXIiNYVSN8BdkgCfbMxP e/jIs+LUfzjSfmw0MgyHLYs= =dTDA -----END PGP SIGNATURE----- --------------enigA10F4A360495E42255A9D604--
