ACPI dump with "USB S3 Wake-Up" disabled

[1.] One line summary of the problem:

Interrupt storm on GPE 0x0D after plugin a device into one of the USB3 after resume on a Samsung NP550P5C laptop.

[2.] Full description of the problem/report:

After I resume the system and plug something in one of the machine's USB3
ports (it doesn't happen if I plug the same device on a USB2 port), the CPU
load raises to over 50%, with one particular process with the highest load:

4 root 20 0 0 0 0 R 50.1 0.0 1:43.63 kworker/0:0

The problem seems to be caused by too many ACPI interrupts:

I can mitigate the problem by disabling that particular source

# echo disable > /sys/firmware/acpi/interrupts/gpe0D

Or by enabling "USB S3 Wake-Up" on the BIOS, in which case the
system works as expected (no storms after resume at all).

The issue was introduced in kernel 3.9 and has been present ever since.
Kernel 3.8 doesn't have the problem.

This bug was present both on Fedora and Ubuntu. A bug was opened on
launchpad and it shows the kernel versions on which the issue is present:

https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1223851

[X.] Other notes, patches, fixes, workarounds:

As mentioned in the full description section, the following command

# echo disable > /sys/firmware/acpi/interrupts/gpe0D

makes the load of the system to drop to normal levels with no apparent
ill-effects, and it is only present if "USB S3 Wake-Up" is DISABLED on the BIOS.

As per Zhang Rui's suggestion, I'm attaching ACPI dumps with the option enabled and disabled.

Comment 5 Agustin Barto 2013-10-18 10:36:13 UTC

An annoying (and potentially dangerous) side-effect of enabling "USB S3 Wake-Up" is that the box turns itself on.

Comment 6 Agustin Barto 2013-11-04 19:08:37 UTC

I tried the latest kernel version (3.12.0-031200-generic) from Ubuntu's kernel PPA and the issue is no longer present.

Comment 7 Agustin Barto 2013-11-05 11:31:31 UTC

Nevermind, the bug is still there on 3.12.0. I had left the "USB S3 Wake-Up" option enabled by mistake.

Comment 8 Agustin Barto 2013-11-13 12:52:58 UTC

The bug is still in the NEEDINFO state. Is there anything else I can do to help?

Added ACPI dumps taken while running Windows 7.

Comment 12 Agustin Barto 2013-11-16 14:22:48 UTC

I found a proper work-around for the problem. I noticed that the ACPI dumps differed when the "USB S3 Wake-Up" was enabled or disabled, so what I took the DSDT for when the option is enabled, recompiled it, and forced it using the instructions given in [1]. I then disabled the option (so the laptop won't turn itself on when it's in the bag). So far, I haven't seen any storms when plunging stuff into the USB3 ports and the box stays off at suspend.

Now I can wait until the bug is fixed or until I manage to get rid of this piece of crap. I'd avoid Samsung laptops if I were you. They're Linux support is atrocious.

I'm attaching the diff between the decompiled DSL files for when the option is enabled and disabled.

Comment 15 Len Brown 2013-12-03 01:13:36 UTC

which USB S3 wakeup setting is the SETUP default?

do you have the capability to apply patches to a test kernel?

Comment 16 Agustin Barto 2013-12-03 01:25:42 UTC

The default value for "USB S3 Wake-Up" is off, and that's when the problem occurs. When it is on, the issue is gone but the notebook wakes itself up.

I can test patches.

Comment 17 Lan Tianyu 2013-12-11 10:05:58 UTC

Since this is a regression, git bisect would be more helpful. Could you bisect between v3.8 and v3.9 and find which commit cause this issue?

Comment 18 Agustin Barto 2013-12-14 01:39:26 UTC

I've bisected the issue to this commit:

    USB: remove CONFIG_USB_SUSPEND option
    
    This patch (as1675) removes the CONFIG_USB_SUSPEND option, essentially
    replacing it everywhere with CONFIG_PM_RUNTIME (except for one place
    in hub.c, where it is replaced with CONFIG_PM because the code needs
    to be used in both runtime and system PM).  The net result is code
    shrinkage and simplification.
    
    There's very little point in keeping CONFIG_USB_SUSPEND because almost
    everybody enables it.  The few that don't will find that the usbcore
    module has gotten somewhat bigger and they will have to take active
    measures if they want to prevent hubs from being runtime suspended.

Comment 20 Lan Tianyu 2013-12-16 07:16:25 UTC

The bisect result show this is a usb bug and so reassign to USB component.

Comment 21 Alan Stern 2013-12-16 15:18:18 UTC

If you build a kernel without commit 84ebc10294a3 (say, a 3.8 kernel) and enable CONFIG_USB_SUSPEND in the configuration, is the problem still present?

I ask because the effect of this commit is basically nothing more than forcing CONFIG_USB_SUSPEND to be always on.  Therefore any bug present with the commit in place should also be present without it.

Comment 22 Agustin Barto 2013-12-16 18:26:05 UTC

I built a 3.8 with CONFIG_USB_SUSPEND and the issue was not present.

Comment 23 Agustin Barto 2013-12-16 19:25:52 UTC

I checked the commit prior to the one I mentioned, but using USB_SUSPEND and the bug is there. Given what 84ebc10294a3d7be4c66f51070b7aedbaa24de9b does, it means that the bug will only present itself when the option is on. I'll bisect again making sure the option is always on.

    ACPI / PCI: Rework the setup and cleanup of device wakeup
    
    Currently, the ACPI wakeup capability of PCI devices is set up
    in two different places, partially in acpi_pci_bind() where
    runtime wakeup is initialized and partially in
    platform_pci_wakeup_init(), where system wakeup is initialized.
    The cleanup is only done in acpi_pci_unbind() and it only covers
    runtime wakeup.
    
    Use the new .setup() and .cleanup() callbacks in struct acpi_bus_type
    to consolidate that code and do the setup and the cleanup each in one
    place.

Comment 27 Alan Stern 2013-12-18 20:20:25 UTC

Okay, go ahead.  I sent an email message to Rafael Wysocki, asking him to look at this.  No response yet.

Comment 28 Rafael J. Wysocki 2013-12-25 22:29:37 UTC

I think that this is a BIOS bug.

What happens is that with "USB S3 Wake-Up" the BIOS doesn't report GPE 0x0D as a wakeup GPE, but still it is used for signaling wakeup after system resume.  It looks like this code path hasn't been sufficiently tested by the BIOS writers.

I'll attach a debug patch in the next comment, please check if it makes any difference.

Comment 30 Agustin Barto 2013-12-26 01:59:51 UTC

The patch fixes the problem. I plugged a device into the USB3 port after resuming and it didn't cause a storm. I tried without the patch just to be safe, and the bug was still there.
