Please excuse the late answer first of all, I was a bit busy
I still don't have a fix for this that works. There has been a fix proposed in honami subforum. I tested, and couldn't note a difference. The wakeup times on wlan are still higher than usual.
As far as I know, and I think I've mentioned this before, this seems to affect all CM based ROMs.
Now, I also have an update for you all
a new OFFICIAL build has been uploaded to basket build for amami :highfive:
You'll find it under Official folder there.
It contains TWRP as ramdisk recovery instead of CM recovery. Also contains the latest updates from M5 kernel, and of course the latest from PAC.
