Version-Release number of selected component (if applicable): Linux Kernel 5.2.5

can select wifi connection from dropdown and automatically connects to home network
Device: Lenovo e485
Wifi chip: realtek RTL8822BE
works in kernel 5.1.x on fedora 30
Created attachment 1601770 [details]
output of lsmod for kernel 5.1.20
Created attachment 1601771 [details]
output of lsmod for kernel 5.2.5
based on the attached output from lsmod it looks like drivers changed from rtw88 and rtwpci from r8822be.
This patch fixes it for me
The previous r8822be driver used msi interupts, the patch above implements them for rtwpci
Card is assigned irq 16 on my laptop (asus gl702zc) but that irq never fires, i its either misconfigured by the bios or outright broken in the card. either way msi works
Thank you for the advice Andrew I will swapped the card with an intel card I had laying around I will test the reltek card on my desktop tomorrow
