    Ok, so color me confused, and maybe I have missed some of the emails or
    skimmed over them too fast (there's been too many of them ;), but

    - I haven't actually seen any traces for this (netconsole apparently
    doesn't work for you, and I'm not surprised: it never really worked
    well for me over suspend/resume either, but I think I saw a mention of
    serial console?)

    - You apparently bisected it down to the range

    0a3fd051c7036ef71b58863f8e5da7c3dabd9d3f <- works
    1d30c33d8d07868199560b24f10ed6280e78a89c <- breaks

    but some of the intermediates in that range didn't compile. Correct?

    Can you try to bisect down a bit more, despite the compile error? Just do

    git bisect start
    git bisect good 0a3fd051c7036ef71b58863f8e5da7c3dabd9d3f
    git bisect bad 1d30c33d8d07868199560b24f10ed6280e78a89c

    and it should pick

    f4d6d004: libata: ignore EH scheduling during initialization

    for you to test. It will apparently break on the fact that "sata_via.c"
    wants "ata_scsi_device_resume/suspend" for the initialization of the
    resume/suspend things in the scsi_host_template, but you should just
    remove those lines, and the compile hopefully completes cleanly after
    that.

    IOW, it *should* be easy enough to pinpoint this from 9 changes down to
    just one.

    Jeff added to the Cc, since he may not have noticed that one of the most
    long-running issues is apparently sata-related.

    (Jeff: David Greaves _also_ had issues with -rc4 due to the SETFXSR
    change, but that should hopefully be resolved and is presumably an
    independent bug. Apart from the fact that "sata_via.c" seems problematic)
