Incorrect initialization of wifi/bt chip in OrangePi 3B official image (linux6.6.0-rc5) #112

I have problem with official image: Orangepi3b_1.0.0_debian_bookworm_desktop_xfce_linux6.6.0-rc5.img Some startups result in incorrect initialization of wifi/bt chip. The short excerpt from dmesg is here:

This issue is caused by incorrect detection of uwe5622 hardware. The first sign of failure in dmesg output is:

[    6.829202] sdiohal:sdiohal_scan_card
[    6.830872] sdiohal:sdiohal_probe: func->class=0, vendor=0x0000, device=0x0000, func_num=0x0001, clock=150000000
[    6.831338] sdiohal err:dt readl fail ret:-110, system_addr=0x4082c208

The workaround is:

diff --git a/drivers/net/wireless/uwe5622/unisocwcn/Makefile b/drivers/net/wireless/uwe5622/unisocwcn/Makefile

 endif

 ifeq ($(CONFIG_AW_WIFI_DEVICE_UWE5622),y)

After disabling of CONFIG_CHECK_DRIVER_BY_CHIPID 100% of startups are successful. The problem and workaround were described in detail here: https://forum.armbian.com/topic/30953-orangepi3b-initial-startup-is-ok-wifi-fails-after-reboot/#comment-173697 (post 4)
