Here's the log I was able to obtain today, dmesg + ftrace at the time
of the crash:

https://bugzilla.kernel.org/attachment.cgi?id=255419

USB keyboard and mouse was plugged when I reproduced this.

Please let me know if you need more info.



Thanks, I'm looking at the logs and so far the most suspicious looking
entry is:

[  257.060941] rtsx_usb-254 0 119946155us : xhci_urb_enqueue:
ep1out-bulk: urb 880105a93300 pipe 3221259520 length 0/12 sgs 0/0 stream
0 flags 0001
[  257.063601] rtsx_usb-254 0 119946162us : xhci_urb_enqueue:
ep0out-control: urb 880105a93300 pipe 2147484928 length 0/0 sgs 0/0
stream 0 flags 0010

It enqueues the same URB, without ever giving it back or actually queuing
any trbs for
the urb, wel,l it might just fail to enqueue it in the first place.

I need to search for a URB that has been dequeued but never given back in
the trace



Ok, found a much more likely candidate:

[  258.004078] kworker/-544 0d..1 121599183us : xhci_urb_dequeue:
ep1out-bulk: urb 880105a930c0 pipe 3221259520...

We try to kill this URB "880105a930c0", twice, and its never given back.
Trace is missing "xhci_dbg_cancel_urb: Cancel URB..." entry in log after
xhci_urb_dequeue, so it never got added to the list for cancellation in xhci
driver.

xhci_urb_dequeue() has one place where it just returns an error without
giving back the urb or queuing it for cancellation.
This is in my opinion a bug in xhci_urb_dequeue()

rtsx_usb_ms is a good test for usb, it seems to be constantly queuing urbs
at all
inappropriate times.

If I write a patch can you try it out?


Yes.

Hi Mathias,

I tested your patch with Linux 4.11-rc3 and can confirm that it solves
the problem.

I've tested suspend and resume with i3lock 150 times and it works.

Thank you, I appreciate it a lot.

Diego




Great, I'll send it forward, it can still make 4.11 final.

Thanks for testing

Thanks, I'm looking at the logs and so far the most suspicious looking entry is:

0 flags 0010

It enqueues the same URB, without ever giving it back or actually queuing any 
trbs for
the urb, wel,l it might just fail to enqueue it in the first place.

I need to search for a URB that has been dequeued but never given back in the 
trace


Ok, found a much more likely candidate:

[  258.004078] kworker/-544 0d..1 121599183us : xhci_urb_dequeue: 
ep1out-bulk: urb 880105a930c0 pipe 3221259520...

We try to kill this URB "880105a930c0", twice, and its never given back.
Trace is missing "xhci_dbg_cancel_urb: Cancel URB..." entry in log after
xhci_urb_dequeue, so it never got added to the list for cancellation in xhci 
driver.

xhci_urb_dequeue() has one place where it just returns an error without
giving back the urb or queuing it for cancellation.
This is in my opinion a bug in xhci_urb_dequeue()

rtsx_usb_ms is a good test for usb, it seems to be constantly queuing urbs at 
all
inappropriate times.

If I write a patch can you try it out?

 I can capture the dmesg with netconsole once the machine hangs, but
 I'm not sure how I could capture /sys/kernel/debug/tracing/trace after
 the hang. I'm unable to use ssh after the hang.

 This is with Linux 4.11.0-rc3-ARCH.

 USB mouse/keyboard was unplugged before booting the machine.

 I didn't do a suspend/resume before getting this trace, should I do that?

 Should I reproduce the hang and get a netconsole dmesg capture with
 tracing enabled?

 4.11-rc2 has better xhci tracing, it shows each URB enqueue and dequeue
 and
 giveback.

 Could you try enabling xhci tracing before suspending (not the same as
 xhci
 verbose dynamic debug)
 It will generate a lot of data, so better to remove all extra USB
 devices.

 xhci tracing can be added with:

 mount -t debugfs none /sys/kernel/debug
 echo xhci-hcd >> /sys/kernel/debug/tracing/set_event

 and then send the output of cat /sys/kernel/debug/tracing/trace

I can capture the dmesg with netconsole once the machine hangs, but
I'm not sure how I could capture /sys/kernel/debug/tracing/trace after
the hang. I'm unable to use ssh after the hang.

A trace and a dmesg of the same  suspend/reusume hang would be great.
And if you can then one of a succesful suspend/resume for reference.

I didn't do a suspend/resume before getting this trace, should I do that?

Should I reproduce the hang and get a netconsole dmesg capture with

From a quick glance it looks like rtsx_usb_ms probaly takes a mutex 
(>dev_mutex)
and then issues a usb_bulk_msg() and waits for it to complete with mutex held.
The usb message times out, usb core kills the urb but the URB probably never 
gets completed,
and function never returns.

Everyting using ucr->dev_mutex would block, for example the kthread, 
rtsx_usb_detect_ms_card
that continuously tries to detect a ms card, takes and releases the same 
ucr->dev_mutex for
each try.

There is a lot going on in xhci during the last suspend befor this.
URBs are canceled, devices reset and re-enumerated, timeout while reading 
descriptor,
device firmware changed.

 It's possible we end up in a situation where xhci never givers back the URB.

4.11-rc2 has better xhci tracing, it shows each URB enqueue and dequeue and 
giveback.

Could you try enabling xhci tracing before suspending (not the same as xhci 
verbose dynamic debug)
It will generate a lot of data, so better to remove all extra USB devices.

xhci tracing can be added with:

mount -t debugfs none /sys/kernel/debug
echo xhci-hcd >> /sys/kernel/debug/tracing/set_event

and then send the output of cat /sys/kernel/debug/tracing/trace

I have had a conversation with oiaohm over IRC about this, some
interesting things he had said about this issue:

2017-03-18 18:08:02 oiaohm  That driver that was going dead
because because it was physical port less was usb stack.   So maybe it
that bit of hardware still doing stupid.

2017-03-18 18:21:44 oiaohm  I guess this current log of yours is
with the realtek memstick black listed.
2017-03-18 18:21:55 oiaohm  because it does not exist.
2017-03-18 18:22:09 oiaohm  physically.

2017-03-18 18:23:04 oiaohm  Maybe.   If the hardware is not inited
the usb stack might not try to suspend it.

2017-03-18 18:26:30 oiaohm  No matter how you look at it the thing
is broken hardware.   I don't know if that realtek is USB 3.0
2017-03-18 18:27:02 oiaohm  Or it sitting on a USB 3.0 hub inside
the machine.

2017-03-18 18:27:39 oiaohm  You cannot expect a driver to work
when the hardware is portless.
2017-03-18 18:27:51 oiaohm  and it should have a port.
2017-03-18 18:27:52 oiaohm  either.

2017-03-18 18:29:03 oiaohm  rtsx_usb_ms this is a memstick driver
there should be  memstick port on you system or a header for a
memstick port both mean the pull down and pull up circiuts are present
so the hardware cannot function right.
2017-03-18 18:29:38 oiaohm  You gone over the machine and there is
no memstick port exposed being a laptop the odds of internal header is
basically never happens.
2017-03-18 18:30:27 oiaohm  so it broken hardware.
2017-03-18 18:31:18 oiaohm  the correct answer with broken
hardware is don't init the part blacklist the driver.

2017-03-18 18:40:36 oiaohm  You can think of it this way the
hardware gets lost because it cannot tell if something is connected so
is sending messages and waiting for responses that will never come.
But when hardware is there due to different speeds of cards it has no
clear clue what the time frame is.
2017-03-18 18:41:27 oiaohm  So the hardware being lost and kinda
jammed is purely to be excepted if it does not have all it required
circuits to function.

2017-03-18 18:48:42 oiaohm  You have the realtek controller for a
memstick port and it cannot tell if the proper hardware is present or
not that is what is triggering the driver to load.
2017-03-18 18:49:18 oiaohm  There is a difference when you have
the USB 3.0 controller active.
2017-03-18 18:49:49 oiaohm  You will see a lot of windows users
noting they need to disable the USB 3.0 controller to hibernate.
2017-03-18 18:50:19 oiaohm  In usb 2.0 the operating system polls
the USB ports and does a lot of the messaging.   In USB 3.0 controller
it does that polling.
2017-03-18 18:50:40 oiaohm  USB 3.0 controllers normally presume
all the hardware that is inited is functional.
2017-03-18 18:51:07 oiaohm  Linux kernel doing USB 2.0 polling
itself presumes the hardware could be busted.
2017-03-18 18:56:37 oiaohm  USB 3.0 controller is interpret driven
to the OS so it does a lot of heavy lifting of USB by itself. USB
2.0 and before controllers are like win modems basically brainless and
depending on the OS todo everything thing.

2017-03-18 18:58:27 oiaohm  So usb 2.0 controller not showing the
issue and the usb 3.0 showing the issue is kind of expected.   If you
did not init the hardware and usb 3.0 controller still showed a issue
then there would be a problem.
2017-03-18 19:02:59 oiaohm  dviola I guess the only thing you were
missing is that the USB 3.0 controller had proper controller so can
think for itself and USB 2.0 and before is like a brainless winmoden
so the OS can work around a few USB hardware issues in USB 2.0
controller mode.

2017-03-18 19:09:58 oiaohm  do remember the difference between usb
2.0 and usb 3.0 at times you have no choice but to force back to usb
2.0
2017-03-18 19:10:12 oiaohm  With broken bits of hardware.

2017-03-18 22:30:38 oiaohm  I think everyone is being confused by
a basic hardware construciton cost

  OK, I've built Linux 4.4.52 (I did a localmodconfig) and rebooted into
  it, I did a suspend/resume and it hanged the first time I tried to
  resume, which isn't much different than using the latest kernel.
 
  My dmesg is still being spammed with these messages:

  xhci_hcd
  [  261.341340] usb 2-1: USB disconnect, device number 17
 
  I guess it's safe to assume at this point that this is a hardware 
  problem?

 That's a good observation!

 It suspect the drivers/memstick/host/rtsx_usb_ms.c isn't behaving
 properly from PM point of view. Perhaps it tries to access its device
 while it from a runtime PM point view still is in a runtime suspended
 state. Exactly why I don't know yet.

Is the rtsx_usb_ms device attached to an xHCI controller?

 OK, I've built Linux 4.4.52 (I did a localmodconfig) and rebooted into
 it, I did a suspend/resume and it hanged the first time I tried to
 resume, which isn't much different than using the latest kernel.

 My dmesg is still being spammed with these messages:

 [  260.043673] usb 2-1: Device not responding to setup address.
 [  260.246918] usb 2-1: device not accepting address 15, error -71
 [  260.633662] usb 2-1: new high-speed USB device number 17 using xhci_hcd
 [  261.341340] usb 2-1: USB disconnect, device number 17

 I guess it's safe to assume at this point that this is a hardware problem?

 Thanks,
 Diego

That's a good observation!

It suspect the drivers/memstick/host/rtsx_usb_ms.c isn't behaving
properly from PM point of view. Perhaps it tries to access its device
while it from a runtime PM point view still is in a runtime suspended
state. Exactly why I don't know yet.

Moreover we have had issues with this driver before and its
corresponding SD card driver in drivers/mmc/host/rtsx_usb_sdmmc.c. On
top of that, both their corresponding devices shares the same usb mfd
device as parent, which is managed by drivers/mfd/rtsx_usb.c.

Unfortunate my knowledge about USB is still in the learning phase,
however I know well about runtime PM ans system suspend, so perhaps I
still might be able to help.

Anyway, I have looped in Alan, let's see if he has some input to this.

 OK, I've built Linux 4.4.52 (I did a localmodconfig) and rebooted into
 it, I did a suspend/resume and it hanged the first time I tried to
 resume, which isn't much different than using the latest kernel.

 My dmesg is still being spammed with these messages:

 [  260.043673] usb 2-1: Device not responding to setup address.
 [  260.246918] usb 2-1: device not accepting address 15, error -71
 [  260.633662] usb 2-1: new high-speed USB device number 17 using xhci_hcd
 [  261.341340] usb 2-1: USB disconnect, device number 17

 I guess it's safe to assume at this point that this is a hardware problem?

 Thanks,
 Diego

That's a good observation!

It suspect the drivers/memstick/host/rtsx_usb_ms.c isn't behaving
properly from PM point of view. Perhaps it tries to access its device
while it from a runtime PM point view still is in a runtime suspended
state. Exactly why I don't know yet.

Moreover we have had issues with this driver before and its
corresponding SD card driver in drivers/mmc/host/rtsx_usb_sdmmc.c. On
top of that, both their corresponding devices shares the same usb mfd
device as parent, which is managed by drivers/mfd/rtsx_usb.c.

Unfortunate my knowledge about USB is still in the learning phase,
however I know well about runtime PM ans system suspend, so perhaps I
still might be able to help.

Anyway, I have looped in Alan, let's see if he has some input to this.

 I found another workaround, I can suspend/resume fine with `i3lock &&
 systemctl suspend` if I disconnect/unplug all my USB devices
 (keyboard, mouse, etc). This with the default settings in the BIOS
 (both USB 2.0 and 3.0 enabled).

 I'm also seeing some messages like this in dmesg:

 [   16.172190] usb 2-6: device descriptor read/64, error -110

 Would this indicate a hardware/firmware/power issue?

According to this document:

http://downloads.dell.com/manuals/all-products/esuprt_laptop/esuprt_inspiron_laptop/inspiron-15-5558-laptop_reference%20guide_en-us.pdf

My computer only has a SD card slot and no MEMSTICK slot.

lsusb says this though:

Maybe the driver gets locked up looking for the MEMSTICK slot?

I've found something interesting and what it seems to be the cause of
my problem.

As soon as I boot my system I can see this process being in the D-state:

[root@myhost ~]# ps aux | grep " D"
root   269  0.0  0.0  0 0 ?D14:11   0:00 [rtsx_usb_ms_2]
root  1424  0.0  0.0  10788  2172 pts/2S+   14:19   0:00 grep  D
[root@myhost ~]#

I'm not exactly sure why that is, but if I do a 'rmmod rtsx_usb_ms'
the problem is gone. I already tried suspending/resuming ~40 times
after I disabled the module and the suspend/resume problem is gone.

 Has any previous kernel ever worked properly before?  If so, any chance
 you can use 'git bisect' to find the offending commit?

OK, I've built Linux 4.4.52 (I did a localmodconfig) and rebooted into
it, I did a suspend/resume and it hanged the first time I tried to
resume, which isn't much different than using the latest kernel.

My dmesg is still being spammed with these messages:

[  260.043673] usb 2-1: Device not responding to setup address.
[  260.246918] usb 2-1: device not accepting address 15, error -71
[  260.633662] usb 2-1: new high-speed USB device number 17 using xhci_hcd
[  261.341340] usb 2-1: USB disconnect, device number 17

I guess it's safe to assume at this point that this is a hardware problem?

Diego

OK, I've built Linux 4.4.52 (I did a localmodconfig) and rebooted into
it, I did a suspend/resume and it hanged the first time I tried to
resume, which isn't much different than using the latest kernel.

My dmesg is still being spammed with these messages:

[  260.043673] usb 2-1: Device not responding to setup address.
[  260.246918] usb 2-1: device not accepting address 15, error -71
[  260.633662] usb 2-1: new high-speed USB device number 17 using xhci_hcd
[  261.341340] usb 2-1: USB disconnect, device number 17

I guess it's safe to assume at this point that this is a hardware problem?

I found another workaround, I can suspend/resume fine with `i3lock &&
systemctl suspend` if I disconnect/unplug all my USB devices
(keyboard, mouse, etc). This with the default settings in the BIOS
(both USB 2.0 and 3.0 enabled).

I'm also seeing some messages like this in dmesg:

[   16.172190] usb 2-6: device descriptor read/64, error -110

Would this indicate a hardware/firmware/power issue?

Thanks,
Diego

I'm not sure, this is my work machine and I've only started using it
recently (since about a month ago or so).

I will try older kernels and see if I get any different results, I
will report back in any case.
