From a89e2ff894bc317a49b9b46ef70eb62e05a8bf7c Mon Sep 17 00:00:00 2001 From: Chris Brandt Date: Thu, 1 Dec 2016 13:32:14 -0500 Subject: [PATCH] sh_eth: remove unchecked interrupts for RZ/A1 [ Upstream commit 33d446dbba4d4d6a77e1e900d434fa99e0f02c86 ] When streaming a lot of data and the RZ/A1 can't keep up, some status bits will get set that are not being checked or cleared which cause the following messages and the Ethernet driver to stop working. This patch fixes that issue. irq 21: nobody cared (try booting with the "irqpoll" option) handlers: [] sh_eth_interrupt Disabling IRQ #21 Fixes: db893473d313a4ad ("sh_eth: Add support for r7s72100") Signed-off-by: Chris Brandt Acked-by: Sergei Shtylyov Signed-off-by: David S.
