Subject: Warning with hda intel registration on sysfs
Date: Fri, 11 Sep 2009 19:28:31 +0200 [thread overview]
Message-ID: <20090911172829.GA4993@nowhere> (raw)
Hi,
It's not a new warning, I got it for a while now, probably since
.29, but it's still there (2.6.31).
I've seen a report about it by the past so I didn't wonder
much. And eventually I've been used to see it.
Tell me if you need my config. I'm currently running a -tip
based kernel but if you need I can send you a config against
vanilla.
Here is the warning:
