    Hello all,

    I have seen this error in the messages file on multiple machines after
    deploying the Recommended Patch Cluster dated March 29, 2005. I did
    not see any of these during our testing before rolling out these
    patches to 20+ production servers. All of these servers are either
    Netra T1 or SunFire V120 servers, Solaris 8, 512 MB memory, 2-36 GB
    SCSI drives and either qfe or GigaSwift ce quad Ethernet cards. I have
    also included the output from "prtconf -v" below.

    I searched the archives and Googled for the error with the result that:

    A. Interrupt 6 typically refers to a network driver issue (but not
    always), and

    B. If anyone else has seen this lately, they haven't figured it out or
    posted a summary.

    I will be more than happy to summarize if someone can point me in the
    right direction to find out more about this warning, or if I can ignore
    the occasional unserviced interrupt.

    Right now, the warnings are making me tired as I have our paging system
    text message me all log entries that have "WARNING" in them...and these
    entries are only happening at 3 and 4 AM :-).

    Here are more details about one specific machine that has had 4 of
    these messages:

    Here are the messages from /var/adm/messages:
