Message-id: <04da01d1d064$7c6efad0$754cf070$@samsung.com> Date: Mon, 27 Jun 2016 16:40:15 +0530 From: PINTU KUMAR <pintu.k@...sung.com> To: linux-kernel@...r.kernel.org, linux-mm@...ck.org, linux-pm@...r.kernel.org, linux-input@...r.kernel.org Cc: pintu.k@...sung.com, vishnu.ps@...sung.com, 'CHANDAN VN' <chandan.vn@...sung.com> Subject: BUG: Kernel 3.10.65: Kernel panic while send-receive MMS on same device Hi, Need a help or some pointer about this issue. Yesterday, received one kernel panic issue on one of our mobile device. Scenario is: Sender is sending an MMS content to its own number. After MMS is received, device vibrates and immediately went into kernel panic. We checked and could not found any problem in our vibrator driver. The PC value itself becomes bad, so we don't have any clue. swapper/1: 0] [c1] PC is at 0x0 swapper/1: 0] [c1] LR is at ns_to_timeval+0x1c/0x34 Following are few details: Processor: ARM Cortex-A7 Quad Core RAM: 1GB Kernel version: 3.10.65 (custom kernel) I know it is custom kernel, but no changes are made related to these areas. It looks like there is some memory corruption issue after returning from the timer handler. It looks to be in the generic code which is similar to the mainline version of 3.10 kernel. If anybody have seen this kind of issue on this kernel version or any other kernel version, please help us how to debug this issue further to find the root cause. If there is already a fix available, please share the details. Even a little pointer also will be helpful. If more information is required, please let us know.
