[nycbug-talk] -current moved from AMD to Celeron, can't build anymore

[Tillman Hodgson]

My old AMD 1800 box was starting to spontaneously reboot just a little
too often for my taste (it appears to be either a RAM or CPU problem) so
I decided to transfer the hard drive to a Celeron 800 box I had handy.

Strangely, the box dumps coreand reboots about 3/4 of hte way through
the boot sequence. Forcing single-user mode, I'm able to bring up the
basics (networking, sshd, etc) and poke around a bike.

I started to suspect that it was my old make.conf that was causing the
problem -- the optimizations may not be appropriate for the Celeron.
This tentative diagnosis was backed up when I tried to perform a
buildworld:

Illegal instructions, that doesn't look good.

The make.conf looked like this:

KERNCONF=BACKFORTY GENERIC
CPUTYPE?=i686
NO_PROFILE= true # Avoid compiling profiled libraries


Does that sound like a reasonable diagnosis? Are there ways to work
around this problem? (I have the 6.0 disc1 CD in the CD-ROM drive,
perhaps I could boot, chroot and build from there? If so, any pointers
as to how?)
