From 1e86240f3fd33f8052141778ad3dffe2c96184d7 Mon Sep 17 00:00:00 2001 From: Michal Schmidt Date: Sun, 30 Jul 2006 03:03:29 -0700 Subject: [PATCH] IDE: Touch NMI watchdog during resume from STR When resuming from suspend-to-RAM, the NMI watchdog detects a lockup in ide_wait_not_busy. Here's a screenshot of the trace taken by a digital camera: http://www.uamt.feec.vutbr.cz/rizeni/pom/DSC03510-2.JPG Let's touch the NMI watchdog in ide_wait_not_busy. The system then resumes correctly from STR.
