Message-ID: <CAAvDm6YWo0urQQU3XWBSFHG6Lo5oGtffBEe6SwcSVBG_B55uOw@mail.gmail.com> (raw)
What are the major differences between soft lockup and hard lockup
which are both detected by watchdog?
Here are some example logs:
1. Watchdog: BUG: soft lockup - CPU#0 stuck for 22s! [cantest:1669]
2. NMI watchdog: Watchdog detected hard LOCKUP on CPU 0
Best regards.
