Subject: [kmemcheck] WARNING: kmemcheck: Caught 32-bit read from uninitialized memory, in  hid_output_report
Date: Fri, 28 Aug 2009 20:45:23 +0100	[thread overview]
Message-ID: <> (raw)

A kmemcheck warning on booting my 2.6.31-rc8 (I haven't tried previous versions -- this was 
actually not the problem I set out to fix).

I can send Jiri (Bcc'ed) or the list a .config if it will help.
