On a Brand new install of Cent OS 7 (Anaconda) I keep getting these error reports:

Message from syslogd@domain  at Sep  2 13:40:33 ...
 kernel:BUG: soft lockup - CPU#0 stuck for 31s! [kworker/0:2:2792]

What is that?

    These are flagged by the Watchdog process that runs automatically.
    ps -ef | grep watchdog

    Open in new window

    Depending on what your system is being used for, these "soft locks" may not be a big deal. You'll want to dissect the entire error message to get a better understanding of what is causing it. It could be an app, drivers, etc.

    It means that your BIOS and Linux misunderstand eachothers powersaving.
    It would be a good idea to update BIOS and reset its settings to defaults.

    I have actually updated the BIOS to the latest from the DELL website (my box) ... is there anything I need to do on the CENT OS box?
