3.13.11-ckt24 -stable review patch. If anyone has any objections, please let me know.
------------------ From: Takashi Iwai <ti...@suse.de> commit fff3b16d2754a061a3549c4307a186423a0128fd upstream. Many harddisks (mostly WD ones) have firmware problems and take too long, more than 10 seconds, to resume from suspend. And this often exceeds the default DPM watchdog timeout (12 seconds), resulting in a kernel panic out of sudden. Since most distros just take the default as is, we should give a bit more safer value. This patch increases the default value from 12 seconds to one minute, which has been confirmed to be long enough for such problematic disks.
