Date: Thu, 25 Sep 2014 16:53:54 +0800 From: zhuyj <zyjzyj2000@...il.com> To: yzhu1 <Yanjun.Zhu@...driver.com>, cjb@...top.org, LKML <linux-kernel@...r.kernel.org> CC: "Wu, Kuaikuai" <Kuaikuai.Wu@...driver.com> Subject: Re: access nand flash and mmc card at the same time on xlp board, there will be many io errors and system will hung The root cause is that: sometimes device can not respond quickly to the request, the timeout mechanism will handle this. Solution: enlarge the device respond timeout to avoid kernel crash. Zhu Yanjun On 09/19/2014 05:06 PM, yzhu1 wrote: > Hi, Chris > > I run a tests on a xlp208 board.
