Hello,

While debugging a kernel module, I get this error and the OS crashes.

[39068.833652] rcu: INFO: rcu_sched self-detected stall on CPU

[39068.834739] watchdog: BUG: soft lockup - CPU#3 stuck for 164s!
[systemd-journal:399]

[39068.834854] watchdog: BUG: soft lockup - CPU#0 stuck for 164s!
[test_axpu_app:2896]

This seems because I stopped the processor for debugging.

How can I avoid this watchdog error during debug?

Any help will be appreciated. Thanks!

 

Chan Kim
