Comment 1 Markus Rechberger 2014-07-18 06:23:42 UTC 
According to the customer in case of an error the debugging function crashes the kernel:

702		xhci_dbg_trace(xhci, trace_xhci_dbg_cancel_urb,
703				"Set TR Deq Ptr cmd, new deq seg = %p (0x%llx dma), "
704				"new deq ptr = %p (0x%llx dma), new cycle = %u",
705				deq_state->new_deq_seg,
706				(unsigned long long)deq_state->new_deq_seg->dma,

Comment 2 Mathias Nyman 2014-07-22 12:42:02 UTC 
As the sundtek report says its probably the find_trb_seg function
that returns NULL. the current TRB can't be found on any segment in the
ring. I don't know how this is possible. Maybe the trb address we are searching for gets corrupted on the way?

Any chance the original bug reporter could add the following debug code, reproduce, and post the output

in a previous test. But I cannot evaluate, if it is important.
Comment 4 Alan 2014-07-29 20:28:19 UTC 
Does this occur if you never load the vbox stuff ?
Comment 5 Markus Rechberger 2014-07-29 20:32:39 UTC 
Yes it also happens without the vbox modules

There's another report of another user:

Created attachment 144751 [details]
testpatch for finding new dequeue pointer

Can you test if this works for you?
Applies on top of 3.16-rc
Comment 7 Dieter Steinwedel 2014-07-31 11:09:59 UTC 
I have tested your patch with 3.16.0-rc7. Unfortunally, the computer is dying silently without any kernel oops or panic, any reaction on inputs and no ssh connection was possible. The only kernel output was:

Jul 31 12:56:38 mc kernel: [  417.489817] xhci_hcd 0000:00:14.0: Failed finding new dequeue state

After the last line the computer died.

Jul 29 19:21:11 mc kernel: [  987.367246] trb not found in segment ffff8800c7aa8de0 

For some reason it tries to search for a trb just recently handled. The trb ffff8800c7ab5800 was already searched, found and moved past. It may be some spurious event pointing to an old trb, and we start to search for it in a new range. search wraps around and fails.

Could you add xhci debugging, reproduce this and send me the ouput.

mount -t debugfs none /sys/kernel/debug
echo -n 'module xhci_hcd =p' > /sys/kernel/debug/dynamic_debug/control

I experienced the same issue when plugging in the sansa clip+ player. This is with Linux 3.15.8 on x86_64:

Comment 11 Sander Jansen 2014-08-11 13:57:36 UTC 
The crash only happens if there's a micro-sdcard plugged into the sansa clip+. Without the sdcard, it works just fine.
Comment 12 Sander Jansen 2014-08-11 14:24:26 UTC 
Never mind my last comment. It happens with and without the sdcard.
Comment 13 Mathias Nyman 2014-08-14 14:51:29 UTC 
Ok, I think I know what's going on. 
Thanks for the logs.

An endpoint halts, returns STALL, we store a pointer to the halted TD to be able to move past it later. The reason for the halt is so bad that device is reset. 
Reset frees all the endpoint rings and allocates new ones.
Later usb_clear_halt() is called, it sees that we stored a halted TD and tries to move the dequeue pointer past it, but it fails to find the halted TD that exists in the old freed ring when searching through the newly allocated ring.

I was working on code that changes the whole way we handle halted endpoints, but it's been slow progress. I'll see if I can finish that code, or if I need to create some quick fix for this first.
Comment 14 Ricardo Ribalda 2014-08-25 16:20:09 UTC

workaround to avoid the crash
Comment 16 Ricardo Ribalda 2014-08-26 16:08:58 UTC 
Could you try if this patch fixes your issue?
Comment 17 Dieter Steinwedel 2014-08-27 12:02:03 UTC 
Unfortunally, my system crashes with your workaround.
Comment 18 Ricardo Ribalda 2014-08-27 12:03:26 UTC 
Full crash or just show the warnings?
Comment 19 Dieter Steinwedel 2014-08-27 12:06:30 UTC 
System halts. I had to power off and on my computer.
Comment 20 Ricardo Ribalda 2014-08-27 12:09:52 UTC 
Could you send dmesg after the patch?
Comment 21 Dieter Steinwedel 2014-08-27 12:21:08 UTC 
I always do "tail -f /var/log/syslog" from a different pc to ensure that I get the last entry from the syslog. In this case my system halts silently without any oops stacktrace. I have no idea, why this happen. I will clean my sources and recompile everthing again to exclude patch errors. That will take some hours.
Comment 22 Dieter Steinwedel 2014-08-27 16:11:54 UTC 
I have cleaned the sources and patched it. The system has crashed and halted anyway. I have got following stacktrace:

Comment 23 Ricardo Ribalda 2014-08-27 16:17:57 UTC 
hmm, I see

Maybe you could:

1) try this: http://marc.info/?l=linux-usb&m=140844993115671&w=2

OR

2) Use may patch against the latest 3.16 (no rc)

Thanks!
Comment 24 Markus Rechberger 2014-08-27 22:14:37 UTC 
By the way we can provide some USB-test devices if needed (the driver uses usbfs, so it's guaranteed that there are no kernelbugs in our drivers - because we have no kernel drivers :-)

the test-procedure is fairly easy just enable/disable the datatransfer, eg. by starting/stopping a TV application -- and even for that no signal is needed.

Give me few days to come up with one more patch to try on top of the latest usb-linus tree, If that doesn't get us any forward I'd be interested in a device
Comment 26 Mathias Nyman 2014-08-29 14:58:08 UTC 
Created attachment 148761 [details]
Testpatch for Fixing NULL pointer deref in xhci_queue_new_dequeue_state

This patch should prevent clearing halted endpoints after device reset
that caused NULL pointer dereferece in xhci_queue_new_dequeue_state.

Patch needs testing, it is done on top Gregs usb-linus branch, applies on 3.17-rc2 and probably on 3.16 as well.

For best performance I recommend first adding patch: 
http://marc.info/?l=linux-usb&m=140844993115671&w=2
but it should work without as well.
Comment 27 Dieter Steinwedel 2014-08-30 15:25:43 UTC 
I have added both patches. Unfortunally, the kernel oopses again. At 17:07 the first usb tuner dies and at 17:11 the second and last usb tuner. Then, the system halts. I wish, I had better news.

Comment 28 Markus Rechberger 2014-08-30 15:30:07 UTC 
can you try following:

/opt/bin/mediaclient --cat /dev/dvb/adapter0/dvr0 > /dev/null

this will keep the datatransfer running all the time. Every additional access to the device will just attach to the currently running session.
Comment 29 Dieter Steinwedel 2014-08-31 19:05:42 UTC 
Markus, it seems to work as workaround.
Comment 30 Markus Rechberger 2014-08-31 21:03:26 UTC 
So the problem is mainly shutting down the datatransfer it puts the Linux USB Stack into an unstable state. The initial transfer seems to be okay.
All the packets are aborted using USBDEVFS_DISCARDURB to make them return immediately.
Comment 31 Mathias Nyman 2014-09-01 10:50:10 UTC 
Ok, I'd be interested in one of those hardwares to debug it locally.
I'll send my contact info to you Markus via mail.
Comment 32 Markus Rechberger 2014-09-10 21:25:23 UTC 
The sample is on the way.
Comment 33 Mathias Nyman 2014-09-29 09:53:19 UTC 
Thanks, I got the hardware, but wasn't able to reproduce the issue.

I was running a script over night over 10h, which runs the mediaclient for 15 seconds, then stops it, and restarts it after 3 seconds. Script looks like this:

#!/bin/bash

while [ 1 ]
do
  /opt/bin/mediaclient --cat /dev/dvb/adapter0/dvr0 | /opt/bin/mediaclient --pipecount=1000 &
  sleep 15
  echo "KILLING mediaclient"
  killall mediaclient
  sleep 3
done

sample output:

KILLING mediaclient
...

device was setup with:
/opt/bin/mediaclient -m DVBT -f 562000000 -b 8

Is there some way to trigger this bug reliably?
Comment 34 Markus Rechberger 2014-09-29 09:56:28 UTC 
Did you test it with a USB 3.0 controller?

Intel NUC systems are affected of that issue for example

Starting / stopping the transfer for 15-20 minutes should trigger this actually.

Also check that no other application is accessing the tuner

/opt/bin/mediaclient --lc  # list clients
Comment 35 Raymond Wooninck 2014-09-29 10:00:06 UTC 
Hi Mathias,

What kernel version was used to reproduce the issue?  

What I have noticed (at least for me when inserting an USB GSM Stick), is that with the 3.17.0-rc5 and later, the crash no longer happens and that I can insert the device reliably and that it works.
Comment 36 Mathias Nyman 2014-09-29 11:19:54 UTC

Comment 37 Markus Rechberger 2014-09-29 16:11:33 UTC 
Also a good way for testing is to use tvtime and switch the channel up / down.

Without a signal source you will get a blue video. This will perform isoc and bulk transfers at the same time, everytime you change a channel it will completely shut down the transfer and restart it.
The transfer allocates around 170 mbit.
Comment 38 Dieter Steinwedel 2014-09-29 17:18:12 UTC 
I use the sundtek tuner in conjunction with mythtv to receiver dvb-c. I have reproduced the bug manually by switching the channel about 80-100 times. In most cases the bug happens after 5-10 minutes. 

I suppose, that you can automate my test above with a bash script. If you are interested in, I would spend some time at the weekend to code it. If you write it on your own, I offer you to test it with my system.
Comment 39 matthias-fick 2014-10-30 21:02:32 UTC 
Hi Matthias,
did you find time to check it again? I would be happy to get a solution. (I'm using a Synology DS114 which has only USB 3.0 ports).
Comment 40 Mathias Nyman 2014-11-04 17:54:01 UTC 
Created attachment 156511 [details]
testpatch v2 for fixing queuing new dequeue state

much expanded and improved version of last fix, turned out
there were several cases not covered by previous pach

I'm still not able to reproduce this myself, so grateful if someone could try it out.
Comment 41 Dieter Steinwedel 2014-11-09 08:04:47 UTC 
Hello Matthias,

unfortunally I had no success. MythTv causes an oops on using the tuner the first time. I have used kernel 3.17.2 only with the patch in attachment 156511 [details]. Is this setup correct?

Comment 42 Mathias Nyman 2014-11-26 12:57:11 UTC 
Yes, thanks, setup seems correct.
Back to the drawing board.

This bug could be a bit similar to bug#65021

I got a testbranch that both fixes some related issues, and adds more debugging for this case. If you can try it out its available at:

git://git.kernel.org/pub/scm/linux/kernel/git/mnyman/xhci.git for-usb-next-test

Remember to switch to the for-usb-next-test branch.

It includes 8 patches that also apply cleanly on top of 3.18-rc6, I can send
just patches instead if you prefer it that way.

I'm hoping these patches would show one of the following messages before it fails:
"Cancelled TD not on stopped ring"
"Cancel URB NOT on current ring"
"Error unhandled cancelled TD's after dev reset"
"Error unhandled TD's after dev reset"
Comment 43 Dieter Steinwedel 2014-11-30 09:59:43 UTC 
Hello Mathias,

I have checked out the sources with following command: 

git clone git://git.kernel.org/pub/scm/linux/kernel/git/mnyman/xhci.git -b for-usb-next-test

Unfortunally I cannot compile the sources.

May you send me the patches?
Comment 44 Mathias Nyman 2014-12-01 11:22:02 UTC 
Created attachment 159321 [details]
8 zipped patches to test dvb bug on 3.18-rc6

Includes both halted endpoint fix and more verbose debugging for dvb issue
Comment 45 Dieter Steinwedel 2014-12-06 16:47:51 UTC 
It really behave strange. With all patches I cannot produce the oops. Normally it happen after max. 5 minutes. Now, have switched the channels more than 30 minutes without an oops. After the test, I have connected my usb3 disk an oops happen:

It seems to be reproducible. After it I started with the unpatched kernel. The pc died silently on zapping. The patches have an impact. Restart and connecting the usb3 hd, only one flapping happened - not reproducible.
Comment 46 Dieter Steinwedel 2014-12-07 16:31:20 UTC 
I have run the patched kernel over night. On the next day, the computer stood still. Fortunally, I found after the reboot following log. The output is shorten, because there are many repeatings.

Comment 47 matthias-fick 2015-01-22 20:41:08 UTC 
Hi,
any news concerning the bug?
Kind regards Matthias
Comment 48 Mathias Nyman 2015-01-23 15:43:46 UTC 
The patches, without the intrusive debug are in 3.18, with some additional new related cleanups in 3.19-rc kernel. 

As I undestood these fixes make the device work from failing in 5minutes
to working. Attaching a usb storage device caused a crash once, not it was not reproducible, and a overnight test caused a hang, but difficult to see what caused the hang here.

Anyone interested in testing the original case with a 3.19-rc5 kernel (or later)
without attaching additional devices and see how that works?

-Mathias
Comment 49 Dieter Steinwedel 2015-01-25 21:49:26 UTC 
I've tested 3.19-rc5 kernel. Later version was not available. I have tested only my usb3 hds. Unfortunally, the have the same behaviour as described above (2014-12-06). 

I have used the usb3 drive at a usb2 port for backup. It works fine for 1-2 hours. After it, the transfer rate increased to 110 mb/s, but the usb3 disk didn't wrote. The backup stopped with an io error. 

If I disable the xhci in the bios, I can do the backup without any errors. I have no idea how to interpret this. May I consider a bios bug?
Comment 50 Mathias Nyman 2015-01-27 14:37:17 UTC 
I think we should regard the additional failing usb3 hdd a separate bug.

In this bug I want to focus on the issues that the bug reporter Markus Rechberger originally described.

Is the sundtek dvb tuner now working with the changes to 3.19-rc5?

in comment #45 it says that the dvb devices work, and channels can be changed
with the additional patches. The same slightly modified patches are also
in 3.19-rc5, and should work as well
Comment 51 Dieter Steinwedel 2015-01-27 17:15:16 UTC 
I have not tested the sundtek dvb tuner with 3.19-rc5. Please wait until next week. I will test it on the weekend.

Will you open the new bug report for the usb3 hdd problem or should I?

Ok Thanks

Better if you can do it. You got the hw setup and can create logs for it.
Comment 53 Dieter Steinwedel 2015-01-31 13:55:26 UTC 
I have tested the dvb tuner. I haven't got an oops. But after more than 250 times switching the channels, I wasn't able to tune a channel. I have disconnected the usb and reconnect it, but no further tuning was possible. I have got following syslog message on disconnect/reconnect:

For me, it looks a little bit like the usb3-hd problem.
Comment 54 Dieter Steinwedel 2015-04-02 18:38:45 UTC 
The usb3-hd problem described on 2014-12-06 is not a software bug but a hardware problem. If I use the usb3 ports on the mainboard, I have not problems with the usb3-hds. If I use the usb3 mainboard adapter cable, I get the problem described on 2014-12-06. It seems so, that I run with usb2 and the adapter cable in futher problems (io errors after an hour).
