    All,

    I am running a SanDisk Compact Flash disk under linux 2.4.21. The
    compact flash SDCFB-256-101-80 works 100%. The problem is this model has
    been discontinued and replaced with an SDCFB-256-201-80. This has a new
    internal controller it would seem. During kernel boot it will attempt to
    detect the partitions on the drive, and hang at this point. The new
    controller seems to support DMA, while the old one didn't. If I disable
    DMA (ide=nodma), then the kernel will not hang, and will boot up
    correctly. However, the drives are unusable. You cannot read/write from
    them. Even an fdisk fails, it displays the partition table but when you
    press 'q' to quit it hangs, and then begins sending kernel debug "hdc
    lost interrupt".

    I also get the following boot messages, which were not present on the
    old model:
    hdc: task_no_data_intr: status=0x51 { DriveReady SeekComplete Error }
    hdc: task_no_data_intr: error=0x04 { DriveStatusError }

    I am running a stock standard 2.4.21.

    Any ideas?

    Regards
      Garth Marran
