    Subjectaic79xx trouble
    Date
    Hello,

    we are just in the process of setting up a new server, which will serve the
    data of an IDE/SCSI raid system (transtec 5008). Some partions of this raid
    device are also mirrored via drbd to a failover system. During a full resync
    of all (3) failover partitions *from* the failover server, the main-server
    first logs many scsi errors and later the access to the raid-partitions
    completely locks up.

    Below is some relevant dmesg output, I already enabled the verbose option for
    the aic79xx driver. Should I also enable debugging, if so, which mode?

    Any help is highly appreciated.


    Thanks in advance,
    Bernd
