Module doesn't display w/ Raspberry Pi kernel 4.19.x

The MMM-SystemStats module works great under Raspbian kernel 4.14.x, but under the 4.19.x kernel installed via "rpi-update", the module fails to display. Whatever the issue may be, MagicMirror successfully presents other modules, and gives no on-screen error... it just doesn't show up among the other modules on screen. Upon reverting back to the 4.14.x kernel, the MMM-SystemStats module again works fine.

Hi Same issue here. But it started after updating this Module yesterday, I'm running raspberrypi 4.14.98-v7. And after SystemStats update, the module doesn't display.

If I try sudo apt-get install rpi-update it say that I already have the newest version installed. So for my setup 4.14.98-v7 is the newest, so think the 4.19.x version you ref. to is a beta/test version.

But still... I got the same issue with the version 4.14.98-v7.

tpbillund - Your "sudo apt-get install rpi-update" is not the same as "sudo rpi-update". Your command updates the rpi-update command itself, whereas the rpi-update command updates the kernel to the latest development release of the kernel.

Whatever issue you may have temporarily had with your "latest" 4.14.x kernel is not the same as with the 4.19.x kernel installed via "sudo rpi-update". Whatever differences there are between the 4.14 and 4.19 tree, whether it's differences to the data available in /proc or whatever, 4.19 seems to break the module.
