Aieee, so the drive doesn't like the new SRST sequence.  Indan pointed
me to your original posting and before the reset sequence update your
drive was reset successfully but only after 30sec delay, right?  If you
change the first entry in ata_eh_reset_timeouts[] table at the top of
libata-eh.c to 35 * HZ, does it work?

Thanks.
