Subject: PATCH: Dell laptop lockup fix for ALSA
Date: Mon, 21 Jun 2004 08:16:47 -0400 [thread overview]
Message-ID: <20040621121647.GA16714@devserv.devel.redhat.com> (raw)
OSS avoids the Dell lockup by not hitting the problem register (which
apparently breaks resume on a Sony laptop). ALSA keeps a flag and uses
pci subvendor info to clear it for problem Dell laptops. Unfortunately
there is at least one other Dell laptop which is affected. This adds
its sub id's
[Patch from Dan Williams @ Red Hat slightly reformatted by me]
