I'm afraid your bisection is incorrect. After quickly looking at the code this looks appropriate, but why does reverting that commit help then? That's a bit odd. Daniel: are you maybe using suspend-to-disk and forgot to mention it? Ciao, Thorsten (wearing his 'the Linux kernel's regression tracker' hat) P.S.: As the Linux kernel's regression tracker I deal with a lot of reports and sometimes miss something important when writing mails like this. If that's the case here, don't hesitate to tell me in a public reply, it's in everyone's interest to set the public record straight.
