Hi Rob,

When you say "master from linux-mti" I presume you mean this tree:

http://git.linux-mips.org/?p=linux-mti.git;a=shortlog;h=refs/heads/master

right?

What FPU problem are you seeing exactly? Could you show us a log for the
failure? Can you post a simple test case which will allow someone to
reproduce it?

(I am also surprised you have ethernet support since the ethernet
support has not reached the mainline tree yet as far as I know
https://git.kernel.org/cgit/linux/kernel/git/gregkh/staging.git/commit/?id=ec3a2207c322e518f7f42c80e54b8ecaf8a6f03e).

Hi Rob,
