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
