From b39f96126549e2834152211a99919917423d2212 Mon Sep 17 00:00:00 2001 From: Kevin Wolf Date: Wed, 13 Mar 2013 16:53:06 +0100 Subject: ide: Reset BMIDEA bit when the bus master is stopped The device is supposed to reset the Bus Master IDE Active bit in the status register when 0 is written to the Start/Stop Bus Master bit in the command register. In the common cases this happens automatically because bdrv_drain_all() flushes the requests, but with a large PRDT it could remain set.
