OK, this is actually NOT a bug…

Kernel works fine (probably it has a i386 support), recompiling it for K6-2 doesn’t make a difference. We have a crash upon running init.

K6-2 machine is a i586 architecture machine, and doesn’t have the CMOV instruction. The libc and gcc utils are builded for a i686 architecture and they use the CMOV-instructions which results to a hang or a kernel panic in i586 machines.

So AFAIK, all K6(-II/-III) machines and VIA C3 -machines and all the other processor without CMOV-instruction won’t work. This information should be in the “hardware compatibility” list.

As a feature request, it shouldn’t be impossible to recompile stuff for i586/i386 and someone really should make a howto for it…
