Subject: What methods or tools could be used to investigate the causes of hard or soft lockup?
Date: Sat, 11 Jul 2020 17:02:01 +0800 [thread overview]
Message-ID: <CAAvDm6bX0iVwjT1M8oBWVEg9x=nKujKAhw57J+fFudmzCVQrcw@mail.gmail.com> (raw)
Hi, list
I have frequently faced sort lockups and hard lockups.
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
What methods or tools could be used to investigate the causes of hard
or soft lockups?
I have been stuck with such problems for a long time.
I would be grateful if somebody shed some light on this issue.
Any advice on how to proceed?
Thank you for your attention to this matter.
Best regards.
