Lenovo ThinkPad L450 Fn keys (including the Fn toggle) don't work after wake from sleep

Yeah, that's what I was about to post. Looks like what I want to achieve can't be achieved with only ACPI patches. So yes, ThinkpadAssistant brings back the rest of the functionality.

Thank you! 

 

Edit: alright. So all the customisations work properly, with ThinkPad Assistant. Everything that's supposed to work, works. Which is great.  However, the very first thing that made me open this thread...which is its functionality after waking from sleep, still doesn't.  

I'm sure there's something that's supposed to do this check, and it fails, but I don't know what am I doing wrong.

Hey guys,

 

Is there a way to check if you have any conflicts in your ACPI patches? Or maybe something missing there? How would you go about debugging this?

@Baio77 Any idea what's going on with the Realtek SD Card Reader kext? 

 

panic(cpu 2 caller 0xffffff801d380f9d): Wake transition timed out after 180 seconds while calling power state change callbacks.

Suspected bundle: science.firewolf.rtsx. Thread 0x3c19.

 

Does it work properly on your hack? What am I missing here? It looks like I'm not the only one with this issue though. And seems to be occurring only with somewhat newer OSes. So, while the driver works...and so far seems to be the only one that actually works, this issue makes me disable the kext for the time being. Cause it crashes in the middle of doing something. Probably only after sleep (since this points to a wake issue)

 

Any idea what could cause this or how to fix it?

 

By the way, the Fn keys issue still occurs. And I can't figure out what causes it. What I noticed is that, after opening the laptop, the Fn key LED indicator blinks once, and that's it. And none of the Fn keys work anymore after that.

 

Update: sp yeah, this seems to only occur after waking from sleep. All good for 3 minutes. After 3 minutes, which seems to be the timeout above, computer restarts, or shuts down completely.
