the USB port stops responding. To recover the port we need to reload
the g_serial module.
I have reports of it happening in the field, on the device but, until
recently, it very hard to reproduce. We found that it is very easy to
reproduce when we use the Microsoft Surface Dock, as hub.

I assume here you few time disconnected and then connected cable and

Actually exception happen in g_serial not dwc2. Why you assume that it

And despite of above exception, g_serial enumerated it works fine?
Please provide me dump of follow dwc2 debugfs's: regdump, hw_params, params.

Indeed. After reporting this, it does sounds it is two decouple
issues. The tty seems to be not properly cleaned up and it seems to
have a resource not properly cleaned up.

If reloaded the USB is detected but tty seems to not work. It seems it
fails to free the ttyGS0 previously used and thus it cannot properly
create the new device.

Do you want this on working and failing state or just the failing one?

Actually, I don't see any issue with dwc2 from the log. Only not clear
why SUSPEND happen hear. Is it because of disconnect/connect or
reloading g_serial?
Is this log recorded when issue seen?
Anyway, before SUSPEND and after dwc2 successfully perform transfers on
all EP's - ep1in bulk, ep2out bulk and ep3in interrupt.
Can you provide dmesg with dwc2 debug prints with exception case inside.

Yes, the log was recorded however we did not reload the g_serial
module. So when we gathered the logs, it was stuck.

The log I sent was taken with:
1) boot device
2) ran 'dmesg -c' so we cleaned the old messages
3) cause the lock up to happen
4) gather dmesg output
What sequence do you want us to do?

I can, however, it is not clear to me what you want us to do.
Should we use, on host side, usbmon? or do you want something different?

Do you have any USB tracer equipment to record trace between host and

I don't. Can we instrument the kernel somehow to gather the info we need?

Reviewed all logs. Not found any dwc2 related issue. Not able to
reproduce on my setup. My log on rmmod g_serial:

Pay attention g_serial twice performing ttySG0 deactivation.
In my setup second deactivation passed Ok, but in your case exception
back trace print out with NULL pointer de-reference on spin_lock_irq.
Could you please add debug print before spin_lock_irq() in function
gs_close() in file u_serial.c to check tty, tty->driver_data. Are these
vars NULL or no.
Just rmmod g_serial case fully enough.
Thanks,
Minas
