I've tried to solve the issue for a couple of hours tonight, and ran into irqpin-related interrupt storms. Guennadi has posted a patch to fix the problem a while ago ("[PATCH 1/3] ARM: shmobile: irqpin: fix handling of spurious interrupts in DT case") but it got rejected. Fixing that might be a prerequisite to get ethernet working correctly. -- Regards, Laurent Pinchart
