This is something to be expected as the mips and mipsel port now
defaults to using R2 instructions set. This means the Loongson 2
CPUs are not supported anymore (this includes the Yeeloong machine).

I have asked many times to document this changes in the release notes,
but this hasn't been done yet. I am therefore reassigning the bug there,
Cc:ing debian-mips so that somone can take care of that.

Thanks,
