        I hope this is going to the right list/group/etc, as I got this email
    address from someone on #kernelnewbies...

        Attempting to mkraid /dev/md0 a raid5 array using a Buslogic Flashpoint
    fast SCSI PCI card will always hard lock the system at exactly 2% complete.
    There is no oops or log, and it's a total lockup. I can't even switch
    virtual terminals when it locks. Using an AHA-2940UW in place of the
    buslogic works perfectly.

        This is using kernel 2.2.17 with the raid 0.90 B0 patch which applied
    cleanly. I was wondering if it was raid, but since the 2940 worked, I
    started to wonder about the Buslogic card driver maybe.

    root@userhost:~# cat /proc/mdstat
    Personalities : [linear] [raid0] [raid1] [raid5]
    read_ahead 1024 sectors
    md0 : active raid5 sdd1[2] sdc1[1] sdb1[0] 4185856 blocks level 5, 4k chunk,
    alg
    orithm 0 [3/3] [UUU] resync=68% finish=17.8min
    unused devices: <none>
    root@userhost:~#

        A cut-and-paste of the rebuild in progress. It completed normally and
    was usable after that on the 2940. I will test any other variations of
    tests I can think of and give the results.

        Any information on even how I can troubleshoot this further would be
    appreciated!

        For replies (If this is a mailing list), please cc: me as well, as I am
    not on the mailing list.
