Everyone seems to be reporting this "illegal instruction" problem lately. I've
seen other replies lately which suggest that this problem is due to lack of
floating point emulation in the kernel. The Hard Hat Linux packages and tool
chain that I use are built with soft floating point support and don't require
kernel fp emulation. So I personally haven't seen these problems.
Make sure that both of your kernel's were built with either CONFIG_FPE_NWFPE=y
xor CONFIG_FPE_FASTFPE=y?
Your problem may be due to lack of fp emulation in the kernel while your
packages and tool chain expect FP support or kernel FP emulation on machines
with no FP?
