Subject: [PATCH 4/5] libata: Print out Status register


commit 35aa7a436c0901fd6f352eff347f58448c141a25
Author: Jeff Garzik <jeff@...zik.org>

    [libata] Print out Status register, if a BSY-sleep takes too long

    We have the info stored in an ata_busy_sleep() variable, so might as
    well print it, and provide some additional diagnostic info.
