NETDEV_WATCHDOG_eth0_smsc95xx_transmit_queue_0_timed_out

[andersthomson]

While compiling latest 4.9.y, I got this one on the console.

Didn't get the first half, but it seems a mmc error (bad card?) got something stuck and ev the networking stuff choked on it. Uninformed guess suggests that their sharing on USB is part of this faith sharing.

Again, without the setup of the device and what you are doing, its going to be difficult to fathom this out.

[andersthomson]

What do you need in terms of setup? The box has two powered usb hubs, two tv cards, two HDs, two serial readers. It's running 4 containers (with tvheadend, nginx, openhab, deamons, and a spare work one). No idea what triggers it. It can happen in the middle of a compile (off the HD), with no TV traffic, so net stuff should be low.

I suspect this is related to #2027. Something has stopped the ethernet driver from emptying its queue in a timely manner.

Note that the SD interface is not USB, so it going wrong as well sort of implies a somewhat wider failure than just the USB.

If this was a one off I suspect it it going to be very difficult to reproduce and hence figure out.

[andersthomson]

It probably is. As it happens, I keep /usr/src/linux on a USB attached HD. I've never seen this one happening again.

[JamesH65]

I'm inclined to close this since its was a one off. If it does turn out to happen again, please reopen and report.
