    SubjectASUS P4PE spurious hdparm -tT results...UPDATE
    hi,

    i'm still getting the same weird negative test
    results for the WDC WD800JB-00CRA1 drive on 2.4.21-pre6:

    /dev/hda:
    Timing buffer-cache reads: -3008 MB in 0.00 seconds = -inf kB/sec
    Timing buffered disk reads: -1504 MB in 0.00 seconds = -inf kB/sec
    Hmm.. suspicious results: probably not enough free memory for a proper test.

    however...i noticed that when i booted up with kernel 2.4.20-xfs_pre6
    (the Gentoo 1.4rc3 LiveCD kernel), i didn't get strange test results.

    the difference between the two seemed to be that the 2.4.20-xfs_pre6 kernel
    initialized the drive in mdma2 mode, and didn't support udma5 for the
    IDE layer in that version of the kernel. so maybe this is a bug that's
    crept in since 2.4.21 and better ICH4 support days?

    the IDE layer in that version of the kernel is based on a version from
    www.linuxdiskcert.org, i'm not sure how different that is from the
    version Alan & c have been working on.

    any ideas what may cause this, for just the WDC drive and not the IBM?
    both are on the same channel..

    thanks,
    leon.
