I finally got to testing this on the laptop from the original bug report.
Both symptoms - "failed to reset PPM!" on startup and and the 50-second hang during resume - are fixed, thank you!
Resuming from sleep often fails to complete on this system (the screen won't turn on, system not responding), but I haven't yet figured out how to reproduce this, and it also happens without the patch (e.g. https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.4-rc5/ ), so I guess it should be tracked separately.

Much appreciated, thanks!
