    Subject[2.5.54] Oops IDE-SCSI and failure AIC7xxx
    Date
    Hello,

    Here is the copy of a boot sequence using kernel 2.5.54 :
    aic7xxx: PCI Device 0:8:0 failed memory mapped test. Using PIO.
    scsi0: PCI error Interrupt at seqaddr = 0x3
    scsi0: Signaled a Target Abort
    scsi0 : Adaptec AIC7XXX EISA/VLB/PCI SCSI HBA DRIVER, Rev 6.2.25
    <Adaptec 2940 Ultra2 SCSI adapter>
    aic7890/91: Ultra2 Wide Channel A, SCSI Id=7, 32/253 SCBs

    (scsi0:A:0): 40.000MB/s transfers (20.000MHz, offset 127, 16bit)
    Vendor: FUJITSU Model: MAN3367MP Rev: 5507
    Type: Direct-Access ANSI SCSI revision: 03
    scsi0:A:0:0: Tagged Queuing enabled. Depth 64
    scsi1 : SCSI host adapter emulation for IDE ATAPI devices
    Vendor: TDK Model: CDRW4800B Rev: S7S3
    Type: CD-ROM ANSI SCSI revision: 02
    ide-scsi: abort called for 21

    *pde = 00000000
    Oops: 0000

    Out of this, two problems :
    - AIC7xxx fails to use DMA, with :
    aic7xxx: PCI Device 0:8:0 failed memory mapped test. Using PIO.
    scsi0: PCI error Interrupt at seqaddr = 0x3
    scsi0: Signaled a Target Abort

    - IDE scsi oops at boot.
