Subject: [PATCH 2.6] clarify why DMA gets disabled on broken drives
Date: Tue, 5 Aug 2003 23:37:08 +0200	[thread overview]
Message-ID: <20030805213708.GC22909@louise.pinerecords.com> (raw)

Bartolomiej,

I just ran into this and had to look at the sources to find out why
the IDE driver was turning off DMA for a particular drive.
