I am seeing these errors on resume when there is a transition of power
state from "AC unplugged" to "AC plugged in" or vice versa.
ata_check_ready() reads the status register which contains the value
0xd0 when the ATA reset error occurs, 0xd0 is not a valid value, and
SRST fails and eventually the error handling routine give up trying to
reset the device. There are some upstream patches to libata but those
dont fix this problem.

Similar problems have been reported on other Laptops and the suggestion
that worked frequently is to change the BIOS setting for SATA from
extendend mode to compatible mode. But the current bios version does not
provide any options to change SATA settings.
