Part Number: DRA821U
Other Parts Discussed in Thread: DRA821
Hi Team,
I am working on a DRA821 processor-based custom board running Linux. During a normal reboot ('reboot' command from Linux userspace), the system shuts down successfully and eventually restarts. However, the following messages are consistently observed during the shutdown sequence:
[ 31.577965] watchdog: watchdog0: nowayout prevents watchdog being stopped!
[ 31.584860] watchdog: watchdog0: watchdog did not stop!
[ 31.600296] systemd-shutdown[1]: Using hardware watchdog 'K3 RTI Watchdog', version 0, device /dev/watchdog0
[ 31.610151] systemd-shutdown[1]: Modifying watchdog hardware timeout is not supported, reusing the programmed timeout.
[ 31.620847] systemd-shutdown[1]: Watchdog running with a hardware timeout of 1min.
...
[ 31.801415] watchdog: watchdog0: nowayout prevents watchdog being stopped!
[ 31.808288] systemd-shutdown[1]: Failed to disable hardware watchdog, ignoring: Device or resource busy
[ 31.817670] watchdog: watchdog0: nowayout prevents watchdog being stopped!
[ 31.824531] watchdog: watchdog0: watchdog did not stop!
...
[ 31.839399] systemd-shutdown[1]: Rebooting.
[ 31.862137] reboot: Restarting system
The system reboots successfully after these messages.
Why does the following message appear during reboot?
systemd-shutdown[1]: Failed to disable hardware watchdog, ignoring: Device or resource busy
Please let us know whether this behavior is expected and if any additional configuration changes are required.
Regards,
Ashwini A
