OK, I retested with the wt-ath 033125 tagged build. This included the
patch the Jeff suggested I try, but the rest of the tree was clean.
Still no 6ghz Wifi. I'm attaching a log file of the boot and first few
seconds with the debug mask turned on. I noticed that if I rmmod the
module and then modprobe it, it complains about not finding
firmware-2.bin, however, I thought that was only for the qcn based
chip? The HW info from dmesg looks like this:
[ 6.070282] ath12k_pci 0000:63:00.0: BAR 0 [mem
0xdd800000-0xdd9fffff 64bit]: assigned

QC_IMAGE_VERSION_STRING=WLAN.HMT.1.0.c5-00481-QCAHMTSWPL_V1.0_V2.0_SILICONZ-
Also, I noticed when looking through the debug logs there are the
occasional WARNING statements from a BUG it appears. They trace back
to the mac.c file inside the ath12k code. There should be some in the
debug log that's attached. Let me know if I can do anything else.
Thanks,
-Walt
