ath11k cannot work correctly in my pc may be due to the problem with board file, as a bug report shown in https://bugzilla.kernel.org/show_bug.cgi?id=215625 Besides the wireless service, it also causes effects on the shutdown speed under kernel 5.17.rc3.22020: When I used Kernel 5.17rc3 with ath11k working, the reboot(shutdown) will be in very slow speed. It takes 3 minutes in average to shutdown in average as i used timer to count. In the first 1.5 minutes the screen may show "[FAILED] Failed to Start Load Kernel Modules", then the whole screen goes black but the system is still running until another 2 minutes is gone. When I add ath11k into blacklist of modprobe.d, the shutdown and reboot speed behaves normally(quickly show the login UI after click reboot button). When I changed Kernel to 5.15 and 5.10.98-1, no matter ath11k is in the blacklist or not, the reboot or the shutdown speed behaved normally. Thus I assume it as a problem with both ath11k and Kernel 5.17.
I suspect this is related to the board file missing which causes delays in ath11k rmmod process.
Everything goes well after I pulled new ath11k files and updated to kernel5.17. Thanks!
