Description Driver coder 2023-07-28 10:22:31 UTC 
Hardware was working OK:
none10@pci0:113:0:0:    class=0x028000 rev=0x00 hdr=0x00 vendor=0x10ec device=0xb852 subvendor=0x10ec subdevice=0xb887
    vendor     = 'Realtek Semiconductor Co., Ltd.'
    class      = network

When try to load the RTW89 driver module(if_rtw89.ko), FW loaded successfully but fails to init rx buf and DMA Rx

dmesg Logs:

Note: Same I have tried it on Linux with same chipset - working fine.

I'll close this as the driver was never officially supported and certain problems have since been overcome by changes from me and others.
So this worked as expected at that time.
