Hi,

I've pi2 used as a headless tvheadend server with two tuners (so lots of USB traffic). Every so often (after a day or two) I get hard hangs of all USB traffic which has prompted me to manually reboot the thing.

I've now enabled the watchdog, configured reboot on panic and gotten myself a serial cable and I now start to see results.

Attached is a large log of where the USB goes south and eventually I get a kernel backtrace triggered by a watchdog codepath somehow.

Any ideas how to fix this?
(grep for 'cut here' for the kernel bits)

How did you enable the watchdog?
This look suspicious

Sep 22 18:06:13 rpi2 systemd-shutdow[1]: Failed to set timeout to 600s: Invalid argument

The hardware watchdog is limited to around 30 seconds I believe due the number of bits in the hardware countdown timer. Ten minutes is very long for a watchdog timeout. 10 seconds would be a more common value.

@andersthomson
Please provide a lsusb -t output of the affected setup.
Are you able to narrow down the affected setup to a minimum setup of connected USB devices?

My "is things in a stable state?" script detected this in dmesg yesterday, which also points to the watchdog.

You appear to have 4 (?!) USB hubs of various sizes plugged into the Pi. Can you post the output of lsusb -t please?

Can you also say whether these hubs are self-powered or bus-powered?

Two self powered hubs off the pi2, one of them is a 10 port with carries three 4way splitters internally.

I got the hubs in an attempt to rule out power issues as I have to (supposedly power hungry) TV tuner sticks in there.

Can you try again after running rpi-update? There have been some bug fixes that may affect your use case.

He'll be referring to top of rpi-4.9.y tree (currently 9a5f215) and using the bcm2709_defconfig.
See: https://www.raspberrypi.org/documentation/linux/kernel/building.md

But it is more useful for us if you test with a default kernel.
Reporting a bug with a custom built kernel adds another level of unknown when we try to diagnose.

@andersthomson are your own builds less stable than rpi-update ones?

@andersthomson In order to keep track of this issue i suggested to open a separate issue for dwc2. I'm interested to get as much as possible dwc2 issues fixed, but unfortunately i'm no USB expert.
It would be helpful in narrowing down the issue, if you reduce the affected device to only 1 device per test. So you could make a good / bad list. I also tried tvheadend, but it's too complex for debugging. Aren't there any simpler commands?

Yes, the mailing lists linux-usb or linux-rpi-kernel would be the right place. But i usually didn't expect so much motiviation. Would be nice if you could provide your scan-dvb cli calls.
