on a freshly reinstalled SLES 11.4 we see this dmesg from /var/crash:

Reinstalled it to check that is it a hw or sw issue, but it still crashes when we run a DSA log (started at ~3500 sec uptime).

The Question: from this dmesg (or any other info) can we determine, what caused the crash? cpu9 error? or driver error maybe?


It looks like upgrading megaraid firmware (AND a ram dimm issue too!) fixed the crash during DSA.

  • hey, why did I got a "-1" ? :( why do people give "-1" without a comment? what did I do wrong? – JoeP87 Apr 27 '18 at 17:25

    I don't think there's anything wrong with your answer. All I can say is that for some reason somebody considered it to be "not useful". My guess is that the down-voter takes an extremist position (that questions-and-answers should always be useful to users other than the OP) - or that they think answers should be more substantial. I think short answers posted as comments are more of a problem for the site. Anyhow, welcome to Unix & Linux. I hope your next interaction with its users is more constructive. Feel free to take the tour and browse the help center. – Anthony Geoghegan Apr 28 '18 at 17:08
