with the rest being as posted before. It gives me:
s 1/2/3 80/50/50 on resume.

With that hunk restored to normal, no change. Resume still works, status
is still 80/50/50.
So, just the "status1 = ata_chk_status(ap);" seems to be enough
to make it work for you, in place of the earlier 500msec delay we started with?
Curious.
Does it still work when the "status1 = ata_chk_status(ap);" is replaced with udelay(1) ??
