From b4159fdc374a1e85d08f316be752bba19af2ad8b Mon Sep 17 00:00:00 2001 From: "jy910.yun" Date: Mon, 15 Apr 2013 14:08:46 +0900 Subject: [PATCH] additional correction regarding haptic deadlock cause : when subthread is waiting to system server, unexpectly thread died. then the system server cannot reply because the receiver already died. solution : before subthread died, it must check whether the sub thread was waiting or not.
