Subject: ath11k_pci: failed to connect to HTT: -110

Hello,

I have Qualcomm QCNFA765.
I am using custom-compiled kernel 6.1.55. I have ath11k_pci in the 
kernel, and all firmware files are loaded successfully. Yet, when 
booting, I see on the console:

ath11k_pci: Service connect timeout
ath11k_pci: failed to connect to HTT: -110
ath11k_pci: failed to start core: -110

and the network device wlan0 does not exist.

But lspci -v shows the network card, and module it is using.

and dmesg | grep ath11k

ath11k_pci: BAR 0: assigned [mem 0x90600000-0x907fffff 64bit]

since I am using custom kernel, it is possible i am missing some kernel 
option. Here is my kernel config

can somebody please tell me what is the problem ?

thank you,
