BUG: soft lockup - CPU#7 stuck

Postby LF42 » 2018/02/11 05:59:17


I have been receiving CPU stuck messages from the kernel, after which the machine appears to lock up.

The messages are of the form:
Feb 10 19:03:09 nas kernel: watchdog: BUG: soft lockup - CPU#7 stuck for 22s! [splunkd:1999]
Feb 10 19:03:09 nas kernel: Call Trace:

Feb 10 19:03:09 nas kernel: entry_SYSCALL_64_after_hwframe+0x21/0x86

Any ideas on how to troubleshoot the problem further?

I have attached the messages file. The messages file starts with the soft lockup messages and then has all of the logs after I hard reset the computer.

Thank you.
