[OnePlus 7, 7 Pro, 7T, 7T Pro Cross Device Kernel D] souri666:
Thanks for this kernel. Using this for a long time on my OnePlus 7T and have been extremely happy with the performance, features and battery life. However, I'm encountering some issues with the latest OOS OB6 for the OnePlus 7T.

Versions:

OnePlus 7T

OOS OB6

Magisk (Latest Stable 20.4)

arter97 Kernel (r58)

Things I've tried:

* Clearing the cache

* Flash stock update (full image) and then flash magisk -> reboot -> Install arter97 kernel (r58) -> reboot

* I dont see any issues upto the point before flashing the kernel

I have also tried using the bluespark kernel over the stock OOS OB6, and don't see these issues there.

Again, I'm not 100% certain this is an issue with the kernel, maybe something related to Magisk. I'm a bit clueless what is going wrong. I'm not sure if I can flash OB5 over OB6, to get rid of these issues and still keep using arter97 kernel.

Details of the issues (from logcat):

A bit at a loss here, can't really understand if the kernel is at fault or Magisk or OB6. Any help is appreciated.
