Debugging spurious wakeup

Debugging spurious wakeup

[Gianluca Anzolin]

Hello,

I have a curious problem with my system: whenever I wake up the PC with a WOL
magic packet and then power it off the systems comes back to life after a
couple of seconds, by itself.

I can reproduce the problem 100% of the times.

I've been having this problems for years. I remember this same issue occurred
also with my previous computer, with a different mainboard. My current system
has an ASUS P8B-WS mb with a Xeon 1275v2 CPU.

I've ruled out in the time many factors: traffic on the net (by disconnecting
the cable), RTC alarms (by disabling them)... long story short: I'm stuck.

While I'm not the only one with this issue (see[1]), some people have reported
mixed success by blacklisting some components (xhci-pci) or by setting
unrelated BIOS options. Unfortunately these workarounds never worked for me.

So I'm here to ask if there is a way to get the source/cause of the last wakeup
by setting some ACPI debug option. This way I could at least pinpoint the
device/interface that caused the spontaneous wakeup and then debug further or
at least disable it.

I've tried to enable the ACPI hardware-related messages with the kernel
arguments: acpi.debug_layer=0x2 acpi.debug_level=0xffffffff

Unfortunately I can't see the information I'm looking for in the resulting
output. Should I enable some other debug_layer? Could anybody point me in the
right direction?

Thank you and best regards,

Gianluca

Hmm, none of them seems to be NIC related, can you please attach the output of lspci -vvxx as well?

Thank you for directions. Here follows what I did:

root@zanac:~$ echo PXSX > /proc/acpi/wakeup
root@zanac:~$ cat /proc/acpi/wakeup | grep PX
PXSX      S4    *disabled
PXSX      S4    *disabled
PXSX      S4    *disabled
PXSX      S4    *disabled
PXSX      S4    *disabled
PXSX      S4    *enabled   pci:0000:04:00.0
PXSX      S4    *enabled   pci:0000:06:00.0
root@zanac:$ poweroff

Then after 2-3 seconds the system turns on.

The echo command didn't work: infact I double checked, it didn't change the
wakeup status.

But if I disabled the wakeup would WOL packets still work?

I ask because if I disable 'Wake-up by PCIe' in the BIOS the system stays off,
but I need the WOL functionality.

Currently ethtool eth0 says:

        Supports Wake-on: pumbg
        Wake-on: g
        Current message level: 0x00000007 (7)
                               drv probe link

This should only allow magic-packets to wake up the system. To be sure I even
disconnected the cable from the NIC. Unfortunately it still turns on by itself.

Thanks,

This is just a debug method to confirm that it is the Ethernet card that brings the system back.

Here follow the commands given:

root@zanac:~$ cat /sys/bus/pci/devices/0000:04:00.0/power/wakeup
enabled
root@zanac:~$ echo disabled > /sys/bus/pci/devices/0000:04:00.0/power/wakeup
root@zanac:~$ cat /sys/bus/pci/devices/0000:04:00.0/power/wakeup
disabled
root@zanac:~$ poweroff

But after a couple of seconds the system still turns on.

A small follow-up.

I looked for the devices with wakeup = enabled and they are:

0000:00:1d.0
0000:04:00.0
0000:05:00.0
0000:05:00.0

For each of them I tried to disable the wakeup with the echo command and then
poweroff, but the system always turns on after a couple of seconds.

I even tried to disable them all to no avail.

Hello,

I'm sorry to bother again but since the previous debug aids didn't go anywhere
I'm here to ask again if there is a command, a debug parameter, something that
could tell me the cause of the last system wake up.

I'm aware that in Windows there is the command "powercfg -lastwake", I need
something similar for linux, since this issue is linux specific (I can't
reproduce it in Windows).

Thank you,

Gianluca

Hello,

since I can reproduce the issue so easily I tried to take the output of lspci
-vvvxxx when the system stays off and when it turns on by itself.

The diff between the two outputs is mainly due to changes of IRQs and
addresses but there is something else:

-               RootSta: PME ReqID 0000, PMEStatus- PMEPending-
+               RootSta: PME ReqID 0400, PMEStatus- PMEPending-

for this entry:

00:1c.5 PCI bridge: Intel Corporation 6 Series/C200 Series Chipset Family PCI
Express Root Port 6 (rev b5) (prog-if 00 [Normal decode])

Basically when PME ReqID is 0400 the system turn on. I don't really know what
that means but I noticed that the PCIe port is connected to the network
controller.

This is the output of lspci -t:

-[0000:00]-+-00.0
           +-01.0-[01]--+-00.0
           |            \-00.1
           +-06.0-[02]--
           +-16.0
           +-1a.0
           +-1b.0
           +-1c.0-[03]--
           +-1c.5-[04]----00.0
           +-1c.6-[05]----00.0
           +-1c.7-[06]----00.0
           +-1d.0
           +-1e.0-[07]----03.0
           +-1f.0
           +-1f.2
           \-1f.3


And this is the entry 04:00.0:

04:00.0 Ethernet controller: Intel Corporation 82574L Gigabit Network
Connection

So it's really the ethernet driver that's misbehaving?

Thank you,

Gianluca

Hi Gianluca,

do yo have the option "Remain off after power failure" in the BIOS ?

Does the issue occur if you set this option ?

Hi,

The BIOS option "Restore AC Power Loss" is set to "Power Off".

The other options are "Last State" and "Power On". I could change it to "Last
State", I can do it later if needed since I've no physical access to the PC
right now.

However I'm beginning to think it's the NIC driver, even though it occurs also
with no cable attached, I sent a while ago an email with my findings.

Thank you,

Gianluca

I suggest you Cc the linux-netdev@, too. If this is related to the 
driver or the NIC itself, someone will probably have an answer for this 
issue.

Re: Debugging spurious wakeup

[Andreas Mohr]

Hi,

[managed to gather proper In-Reply-To from spinics.net
rather than broken lkml.org]

I'm having a very similar issue with my PCI FireWire card:
whenever shutting down or even suspending,
I'm getting immediate spurious wakeup; currently most strongly suspecting
Firewire PHY-related IRQ event wakeups.

I collected the following items so far:
- asked for help (having the system properly record / retain the actual
  reason for system-global wakeup):
    "pm: record / retain actual reason of last system wakeup??"
      https://lkml.org/lkml/2015/6/2/625
- figured out that it can be silenced with *general* (ouch)
  BIOS PCI wakeup disable, yet that if not disabled
  (which is *very* desirable, obviously, to retain WOL capability etc.)
  it's actually already in a broken state directly post-BIOS-init,
  at LILO prompt (i.e., **NOT** in Linux, NOT a Linux driver issue!
  However perhaps we *might* be able to do something about it in Linux...):
    "fw-ohci: ALi M52xx unsupported"
      https://bugzilla.kernel.org/show_bug.cgi?id=10935
    (contains reference to http://www.tonymacx86.com/general-help/65531-gigabyte-uefi-bios-startech-firewire-pcie-card-sleep-wake-shutdown-restart-issues-thread-8.html
    where tons of people have issues with various FireWire cards -
    so it seems that this is an issue that's pretty much inherent
    to / associated with FireWire hardware behaviour)
- found 074_GPE_Routing.doc which explains these GPE / PME things
  (this *is* the stuff that's broken/problematic here, right??)
  in pretty detailed form
- "Re: PME# for add-on cards"
    http://markmail.org/message/7uuzqbtrpswzrezz
  mentions that probably BIOS forgot to do PME masking
  directly prior to activating hardware shutdown
  (well, at least in my case, where wakeup happens completely instantly,
  as opposed to your case where it will wakeup after a couple seconds)

No amount of fumbling (~1 hour) with CAP_PM register range
(PME_EN etc.; "setpci -v -s ${dst} CAP_PM+4.b=XX")
or e.g. setting the "remove" sysfs attribute of PCI (sub) devices
(this would then be a nicely controlled i.e. fine-grained manner)
so far managed to disable this behaviour.
I suspect that we might be talking
of simple complete signal level mal-functioning of the card
irrespective of how it's actually configured
to generate or not generate events...
(shutdown --> power change --> floating signals on PME# --> wakeup)
I also tried to completely mask all FireWire event types in driver-side
suspend handler, with no success (but given that this is a combo card
with various USB host controllers FireWire may not be the sub device to
be blamed after all - here we are again at dearly needing
system-provided information about the *maximally precise* reason
of last wakeup - PME ReqID [not available on my Conventional PCI system]
seems to be a prime candidate). But given that the Mac forum reports issues
with many FireWire cards, faulty USB sub device seems less likely.

So, I'm still quite far from possibly(!) being able
to create a device-specific PCI quirk entry (drivers/pci/quirks.c)
or to create driver-side workarounds
for FireWire cards which have this issue.

HTH,

Andreas Mohr

I don't know if the issue is the same as mine. In that case it wouldn't
be driver related. As explained before, for me the spontaneous wakeups
occur after a Wake-on-Lan but not when powering up the system by other
means (i.e. power button).

As suggested I asked on netdev but got no reply at all, so I'm on my own
right now.

Thank you for sharing your experience, the document about GPE and PME
seems useful to pinpoint the issue: as explained in another email, I
found a difference in lspci when the undesired wakeup occurs and it
involves PME signals:

-		RootSta: PME ReqID 0000, PMEStatus- PMEPending-
+		RootSta: PME ReqID 0400, PMEStatus- PMEPending-

The problem is, these difference is not related to the network PCI
device but to the PCI bridge behind which the network device sits.

If I find something useful (unlikely, but never lose the hope) I'll send
an update :)

Thank you,

Gianluca

Re: Debugging spurious wakeup

[Gianluca Anzolin]

Hello,

Yesterday I took the time to read the document about GPE / PME handling and I
compared the wakeup code of my BIOS with the examples in that document.

I noticed that some vital wakeup code was executed only when a variable (PMSX)
was set. That variable was set by a global NPME() method and that method was
called by _OSC().

And in my logs I had this message:

giu 19 18:31:06 zanac kernel: acpi PNP0A08:00: _OSC: OS supports
[ExtendedConfig ASPM ClockPM Segments MSI]
giu 19 18:31:06 zanac kernel: \_SB_.PCI0:_OSC invalid UUID
giu 19 18:31:06 zanac kernel: _OSC request data:1 1f 0
giu 19 18:31:06 zanac kernel: acpi PNP0A08:00: _OSC failed (AE_ERROR);
disabling ASPM

A googled a bit and found the following bugzilla entry, that applies to my
situation perfectly: the NEXP variable isn't set anywhere, yet in Windows it
is.

https://bugzilla.kernel.org/show_bug.cgi?id=36932

So I disassembled the DSDT, I removed any test involving the NEXP variable in
the code, I recompiled and replaced the table with GRUB.

And then the _OSC() invocation completed successfully, giving me a working WOL
without spontaneous wakeups!

What puzzles me is that the location of the NEXP variables is marked as ACPI
NVS and the kernel never touches that region of memory. What is Windows doing
differently that makes it work?

However I consider the issue solved now. I leave also the link to the Arch
forum post where I describe in detail what I did for future reference.

https://bbs.archlinux.org/viewtopic.php?pid=1538895#p1538895

The document 074_GPE_Routing.doc proved very useful and I want to thank you for
your hints and the help I got from people in this mailing list.

Gianluca

PS: the PME ReqID marks the source of the latest wakeup and was then a lead of
the device responsible for the wakeup. But the problem was elsewhere...

Great work and thanks for sharing you results !

Perhaps it is not Windows itself but the motherboard driver fixing a 
known bug ?
