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 [ 6.070310] ath12k_pci 0000:63:00.0: enabling device (0000 -> 0002) [ 6.071249] ath12k_pci 0000:63:00.0: MSI vectors: 16 [ 6.071254] ath12k_pci 0000:63:00.0: Hardware name: wcn7850 hw2.0 [ 6.596331] ath12k_pci 0000:63:00.0: qmi dma allocation failed (7077888 B type 1), will try later with sma ll size [ 6.604041] ath12k_pci 0000:63:00.0: chip_id 0x2 chip_family 0x4 board_id 0xff soc_id 0x40170200 [ 6.604044] ath12k_pci 0000:63:00.0: fw_version 0x100301e1 fw_build_timestamp 2023-12-06 04:05 fw_build_id 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
