Subject[PATCH] softlockup: re-increase hung tasks check from 2 minutes to 8 minutes
 Commit e162b39a, which moved the soft lockup code around a bit,
accidentally reverted commit fb822db4, which extended the soft lockup
timeout from 2 minutes to 8 minutes.

This patch restores it to 8 minutes.

From the original patch:
>Andrew says:
>
>> Seems that about 100% of the reports we get of this warning triggering
>> are sys_sync, transaction commit, etc.
>
>increase the timeout. If it still triggers for people, we can kill it.
