Message-ID: <CAE7DoPYi=GJknqTYG34v9H0gS8pp_TgNxTbr6Mi5PikTYmHHvA@mail.gmail.com> Date: Thu, 5 Nov 2015 11:06:17 -0600 From: Ben Gardner <gardner.ben@...il.com> To: linux-kernel@...r.kernel.org, linux-acpi@...r.kernel.org Subject: BayTrial: 137 sec delay on boot - power button resumes Hi all, I have an BayTrail-I E3845 SoC that will occasionally (~5%) pause for 137 seconds on cold boot. The first log after it continues is this one: clocksource: tsc: mask: 0xffffffffffffffff max_cycles: 0x372ab6ee016, max_idle_ns: 881590685180 ns The typical logs before the hang are below. This is with Linux 4.2.4, x86_64. There are two data points that I think are relevant to this problem. 1) If I press the power button while it is in this "hung" state, it immediately resumes booting. The power button is configured to generate an ACPI interrupt. 2) If I turn up logging to the console by adding "debug" to the kernel command line, this hang does not occur. 3) HPET is (incorrectly?) disabled in early-quirks.c for this CPU due to S0ix issues. This CPU (Bay Trail-I) does not support S0ix. It sounds to me like some sort of race condition that leads to a dropped interrupt. I haven't yet tracked down where it is stuck waiting, but I suspect some sort of clock calibration loop using the ACPI timer. Any ideas where I should start looking? I'm hoping the "137 seconds" will be an obvious clue to someone.
