Since a years ago I know that there is a firmware fix for this issue, but it
was not public.
I know firmwares are leaked in station-drivers and finally I decided to give it
a try following the excellent guide by this guy:
this is dmidecode output of my machine, in case the fix is FW related,
it may be useful in order to contact the motherboard vendor

Hello,
I am unable to test with the kernel you provided, because my tuner card
doesn't have driver in mainline kernel tree. So I have to compile it
myself and I need kernel headers for this.
So I compiled kernel 4.16 from debian linux-source-4.16 package and
applied the patch you provided:
Hello,
I think I am ready with the trace log. Hopefully it is full, because machine

Interesting is that it took ~12 hours to crash it this time.
The problem with ssh access is that this is virtual machine under XEN
and when you

Is this correct command to get traces?
I will run it in advance.

I will be back later with the logs.
Thanks for your help.

Hello,
Looks like I am having the same problem.
After some hours(random time) my USB 3.1 asmedia controller crashes the driver
with following error:
[ 873.661534] xhci_hcd :00:00.0: ERROR Transfer event TRB DMA ptr not part
of current TD ep_index 0 comp_code 3
[ 873.661629] xhci_hcd
Ok.
Can you please tell me the homepage of linux-usb mailing list so I can
subscribe. Google returned many results:
spinics linux-usb marc.info .. which one is the correct and current linux-usb

Thanks for your answer Kai-Heng.
I am not sure what ftrace is. I used these commands to get the logs:
mount -t debugfs none /sys/kernel/debug
echo xhci-hcd >> /sys/kernel/debug/tracing/set_event
cat /sys/kernel/debug/tracing/trace
Can they be used to debug this? Or there is another procedure?
Hello,
I still have the bug with the patch presented here and kernel 4.12.2. (I am on
debian):
https://git.kernel.org/pub/scm/linux/kernel/git/mnyman/xhci.git/commit/?h=for-usb-linus=353a73c757c0b856bb95f5e73cf41b10b685258d
If that is the latest patch, it applies successfully on 4.12.2 but
Sorry, I meant bug: 1667750
I wanted to say that I believe 1663975 and 1667750 are same bug.

I have the same problem with my USB 3.1 controller:

I passthru the controller to XEN VM. I then connect to it USB TV Tuner card.
I am using VDR software which is TV software that when not in use is scanning
