    How much RAM is in your machine? There's a known problem with sata_nv
    ADMA with ATAPI devices and over 4GB of RAM. As a temporary workaround,
    you can boot with sata_nv.adma=0 on the kernel command line, or limit
    your memory with the mem= command line option so that memory over 4GB is
    not used.

    I don't know about kernel.org Bugzilla, but there's a Red Hat Bugzilla
    entry here:
