    SubjectRe: Scsi problems in 2.5.1-pre9

    Hi Jens,

    I just booted 2.5.1-pre10 on ppc64 and still get the errors:

    Incorrect number of segments after building list
    counted 3, received 2
    req nr_sec 24, cur_nr_sec 8

    This seems to be happening because we now allow sg merging through
    the BIOVEC_MERGEABLE macro. On ppc64 (and sparc64) we can coalesce two
    sg entries if the first one ends on a page boundary and the next one
    starts on a page boundary because we have an IO MMU. (I know that you
    know this, Im just explaining it for those who dont :)

    Should we just remove the warning now?
