    Server crashing, possible driver issue


    Greetings,
    My server has been crashing on a nightly basis the last few nights. It doesn't come back up automatically either, my host has to manually restart it. I did an update to CentOS last week, but no new software was installed (I just did a yum update). I had no issues before I did the update. In the logs the following appears during the crash,
    WARNING: at net/sched/sch_generic.c:261 dev_watchdog+0x26b/0x280() (Tainted: P --------------- )
    I did some Googleing and it appears to be a network driver related issue, but I had trouble finding a fix.
    The server is a Supermicro SuperServer 5017C-MTF
    Has anyone here seen anything like this?
    I really appreciate your help!
    Thank you!

    What activity are your logs showing prior to the crash?
    Do you have your BIOS set to reboot?
    What things did the update change, especially with a server you need check what an update change can't just automaticly say yes.
    I'd say if a network driver you wouldn't be connecting at all, maybe a memory leak from the update.
    Does the crash keep happening at the same time?
