Hi,

Many thanks for the report 👍

Known issue (apologies forgot to list it), should be resolved with 4.20 kernel. We need to wait :)

@Fourdee
Hi,
I suspected it, but couldn't find any reference. I'll gladly wait for the next release, thank you.

@Maldus512
Has been a while. Meantime Fourdee created a new image with newer kernel. I hope suspend to RAM works well with this.

Another new image based on Debian Buster is ready for testing: https://github.com/MichaIng/DietPi/issues/2979

I mark this issue as closed due to missing reply. Feel free to reopen it is still present with Buster beta image.
