    SubjectIDE lockup after floppy access
    After accessing a floppy disk, the kernel blocks on the first harddisk
    access. After a couple of seconds, the following messages appear:

    hda: dma_time_expiry: dma status = 0x61
    hda: DMA timeout error

    I can only reset at this point. This is reproducible. I'm running
    kernel 2.6.0-test9 on an SMP system, but the problem doesn't go away
    when I boot with "nosmp". The kernel was built with CONFIG_PREEMPT.
    Here are the IDE startup messages:

    Uniform Multi-Platform E-IDE driver Revision: 7.00alpha2
    ide: Assuming 33MHz system bus speed for PIO modes; override with
    PIIX4: IDE controller at PCI slot 0000:00:07.1
