Description

Hi

On Raspberry Pi 3 Model B Plus with the latest git of tvheadend, I am getting the following error.
This is on up-to date arch arm.

Its worth to mention that I have the same problem on the same pi with a tvheadend build in January 2018.

Updated by Dave Pickles over 6 years ago

It's a known problem in the Linux kernel - see https://github.com/raspberrypi/linux/issues/2446 You can patch the kernel if you are able to build your own (it's really not difficult on Arch), or wait for an official fix - it's not in 4.14.28.

Thank you for the information, I'll wait for the next kernel package.
