Subject: NOHZ tick-stop error with ath10k SDIO
Date: Wed, 18 Aug 2021 12:18:25 -0300 [thread overview]
Message-ID: <CAOMZO5AAvZic-NFbYYSVfOxY-27QukXMX68f9eDmhbqAkBRKRw@mail.gmail.com> (raw)
Hi,
When launching the hostapd application on a i.MX7 based board with an
ath10k device connected via SDIO, the following "NOHZ tick-stop error"
messages are seen:
# hostapd /etc/wifi.conf
Configuration file: /etc/wifi.conf
wlan0: interface state UNINITIALIZED->COUNTRY_UPDATE
[ 63.021149] NOHZ tick-stop error: Non-RCU local softirq work is

This happens on all kernel versions from 5.10 to 5.13.
Any ideas on how to fix this problem?
Thanks,
Fabio Estevam
