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). -- markos From mboxrd@z Thu Jan 1 00:00:00 1970 Received: from mailapp01.imgtec.com ([195.59.15.196]:52402 "EHLO mailapp01.imgtec.com" rhost-flags-OK-OK-OK-OK) by eddie.linux-mips.org with ESMTP id S6842569AbaGVOVm0zoZ8 (ORCPT ); Tue, 22 Jul 2014 16:21:42 +0200 Message-ID: <53CE736E.1060009@imgtec.com> Date: Tue, 22 Jul 2014 15:21:34 +0100 From: Markos Chandras MIME-Version: 1.0 Subject: Re: EdgeRouter Pro supported?
