Comment 25 for bug 257790

Thanks Lars. I'm just pasting the upstream git commit id below for the kernel team to reference. Indeed as Lars mentioned, this will be included by default in Karmic. I'll approve the Jaunty nomination for a SRU - stable release update. This patch will also likely be available in the upstream 2.6.30-rc3 mainline kernel build once it is released so you may want to keep an eye out for that to test - https://wiki.ubuntu.com/KernelMainlineBuilds

    libata: handle SEMB signature better

    WDC WD1600JS-62MHB5 successfully hits the window between ATA/ATAPI-7
    and Serial ATA II standards and reports 3c/c3 signature which now is
    assigned to SEMB. Make ata_dev_classify() report ATA_DEV_SEMB on the
    sig and let ata_dev_read_id() work around it by trying IDENTIFY once.

    This fixes bko#11579.
