Hi, I am using the QCA9377 chip on an imx6dl-pico-pi board running kernel 5.10.37 and I noticed that the firmware takes a long time to load (more than 3 minutes after boot): [ 192.544227] ath10k_sdio mmc1:0001:1: qca9377 hw1.1 sdio target 0x05020001 chip_id 0x00000000 sub 0000:0000 [ 192.554451] ath10k_sdio mmc1:0001:1: kconfig debug 0 debugfs 0 tracing 0 dfs 0 testmode 0 [ 192.566465] ath10k_sdio mmc1:0001:1: firmware ver WLAN.TF.1.1.1-00061-QCATFSWPZ-1 api 5 features ignore-otp crc32 7746e551 [ 192.765756] ath10k_sdio mmc1:0001:1: failed to fetch board data for bus=sdio,vendor=0271,device=0701,subsystem-vendor=0000,subsystem-device=0000 from ath10k/QCA9377/hw1.0/board-2.bin [ 192.784424] ath10k_sdio mmc1:0001:1: board_file api 1 bmi_id N/A crc32 544289f7 [ 194.081698] ath10k_sdio mmc1:0001:1: htt-ver 3.32 wmi-op 4 htt-op 3 cal otp max-sta 32 raw 0 hwcrypto 1 [ 194.160101] mmc1: queuing unknown CIS tuple 0x01 (3 bytes) [ 194.177321] mmc1: queuing unknown CIS tuple 0x1a (5 bytes) [ 194.187873] mmc1: queuing unknown CIS tuple 0x1b (8 bytes) [ 194.194279] mmc1: queuing unknown CIS tuple 0x14 (0 bytes) And then when I try to use it the following RCU messages are seen: # wpa_supplicant -iwlan0 -c /etc/wpa.conf & # Successfully initialized wpa_supplicant [ 234.360447] NOHZ tick-stop error: Non-RCU local softirq work is pending, handler #08!!!

I have also tested 5.12.4 with the same results. Using the QCA9377 firmware from the latest linux-firmware tree. Thanks, Fabio Estevam
