This one and the previous linux-next can't resume from suspend to RAM on my
HP nx6325.  The problem is reliably reproducible 100% of the time.

The patch that causes it to happen, as identified by bisection, is:

commit 3dcefa9419f3b8a49921d2218c93a3ddba8e0855
Author: Bartlomiej Zolnierkiewicz <[email-masked]>

    ide: use __generic_unplug_device() in ide_do_drive_cmd()

    Cc: Borislav Petkov <[email-masked]>
    Cc: Jens Axboe <[email-masked]>

Reverting it along with the next IDE patches (up to and including
commit fd42e6df0fd163411f5c655b4bde4fb6a8910edc
"ide: remove action argument in ide_do_drive_cmd") makes the problem go away.

Thanks,
