    Hi!

    I'm running an Intel SE7500CW2 board (Dual Xeon 2.4 w/ ht and 4GB RAM).
    It has an on-board Promise PDC20267 UDMA Raid controller that
    recognizes a mirror set and finds both disks but looses the second one
    at boot:

    SMP: AP CPU #1 Launched!
    SMP: AP CPU #3 Launched!
    SMP: AP CPU #2 Launched!
    ad6: WARNING - READ_DMA recovered from missing interrupt

    ad0 is connected to the on-board controller that only supports UDMA33 so
    that is no problem.

    The problem is the raid:
    [0.04] root@cave:~ > atacontrol status ar0
    ar0: ATA RAID1 subdisks: ad4 DOWN status: DEGRADED
    [0.03] root@cave:~ > atacontrol list
    ATA channel 0:
        Master: ad0 <Maxtor 4G160J8/GAK81CK0> ATA/ATAPI rev 6
        Slave: no device present
    ATA channel 1:
        Master: acd0 <CD-224E/2.9B> ATA/ATAPI rev 4
        Slave: no device present
    ATA channel 2:
        Master: ad4 <Maxtor 4G160J8/GAK819K0> ATA/ATAPI rev 6
        Slave: no device present
    ATA channel 3:
        Master: ad6 <Maxtor 4G160J8/GAK819K0> ATA/ATAPI rev 6
        Slave: no device present
    [0.03] root@cave:~ >

    Using atacontrol detach und attach I can rescan channel 3 but the drive
    automatically reports the same error and thus the mirror is not rebuild.

    The same behaviour (but due to missing ATAng with different messages) can
    be observed on 5.1-RELEASE.
