First part sounds very much as if your *kernel* is built for too "high"
a processor (e.g. i686 when you've only got i586). I've seen people
suggest that K6s will run i686 code, but I've never tried it myself
(CONFIG_M586 or CONFIG_MK6, depending on age of kernel and version of
gcc), and others who post that it definitely doesn't support the cmov
instruction. It might even differ between the k6, k6/2, k6/3 for all I
Vendor kernels for mdk and I believe Suse are i586, RH used to ship
with i386 and i686, don't know about fedora.
The only thing against this is the "boot from installed system"
utility. When you use that, does it use your LFS kernel, or does it use
its own kernel ?
