    I get this when DMA is enabled:

    Oct 20 15:39:07 cr753963-a kernel: hdb: timeout waiting for DMA
    Oct 20 15:39:07 cr753963-a kernel: hdb: irq timeout: status=0x6e {
    DriveReady DeviceFault DataRequest CorrectedError Index }
    ide0: reset: success
    Oct 20 15:39:07 cr753963-a kernel: hdb: DMA disabled
    Oct 20 15:39:07 cr753963-a kernel: ide0: reset: success

    It only happens when there lots of data is being transferred, or compiled
    on the drive.. The drive status is this:

    /dev/hdb:

     Model=Maxtor 82560A4, FwRev=AA8Z2726, SerialNo=C40LTQGA
     Config={ Fixed }
     RawCHS=4962/16/63, TrkSize=0, SectSize=0, ECCbytes=20
     BuffType=DualPortCache, BuffSize=256kB, MaxMultSect=16, MultSect=off
     CurCHS=4962/16/63, CurSects=5001696, LBA=yes, LBAsects=5001728
     IORDY=on/off, tPIO={min:120,w/IORDY:120}, tDMA={min:120,rec:120}
     PIO modes: pio0 pio1 pio2 pio3 pio4
     DMA modes: mdma0 mdma1 *mdma2
