Yes, but it seems you never get as far as loading the board file so I
don't think that one's involved here.

Ok, so you do have a different chip_id than I do (0x2 instead of 0x12),
but both ids have an entry in board-2.bin (otherwise it would not work
"sometimes"):
ath11k_pci 0006:01:00.0: chip_id 0x2 chip_family 0xb board_id 0x8c soc_id 0x400c0210
You could compare it with what the chip in your other machine which does
not have this issue is identified as (compare all the values above).

Ok, got it. But with 5.19 you never saw this issue at all?

Ok, the fw version is also logged on successful probe and you appear to
use the same version as I do:
ath11k_pci 0006:01:00.0: fw_version 0x110b196e fw_build_timestamp 2022-12-22 12:54 fw_build_id WLAN.HSP.1.1-03125-QCAHSPSWPL_V1_V2_SILICONZ_LITE-3.6510.23
Could you check what fw version you were using with your 5.19 iso image?

Hmm... Not sure what's going on here, and I'm afraid I won't have time
to look at this myself for a while.
