Re: T2 build for SiS 55x System-on-a-chip

Hi,

from a quick glance it could be an "over-optimized" kernel utilizing
instructions not "implemented" in the CPU silicon. E.g. the Pentium
Pro CMOV, NOP, etc.

Can you check that you did not optimize your kernel for 686, Pentium
Pro or higher? Instead use just 586, or even 486 depending which
instructions really are available on this SiS CPU.
