Subject: [PATCH] IP32 power button fix for 2.6.30
Date: Thu, 14 May 2009 11:29:27 -0700 (PDT)	[thread overview]
Message-ID: <273990.30979.qm@web65307.mail.ac2.yahoo.com> (raw)



I think i run into same sort of problem, as described here:

http://lkml.org/lkml/2009/4/16/24
http://lkml.org/lkml/2009/4/14/94

(in my case it was hang after pressing O2's power button)

this patch fixes it:

        debounce_timer.function = debounce;
        debounce_timer.expires = jiffies + 50;

tested with 2.6.30-rc5 mainline (linux-mips.org tree was also affected)
