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):

Ok, I replaced eudev with mdev in Buildroot and now it loads the
QCA9377 firmware quickly.

# wpa_supplicant  -iwlan0 -c /etc/wpa.conf &
# Successfully initialized wpa_supplicant

[  234.390478] NOHZ tick-stop error: Non-RCU local softirq work is

These NOHZ messages still pop up.

Cheers
