--- Comment #3 from icanrealizeum ---
Ok, now that the cache error doesn't happen and reboot works, I've tested
shutdown and it now fails at the "Stopping disk" part, which means this line:
sd_start_stop_device(sdkp, 0);
ata4.00: failed command: STANDBY IMMEDIATE

So now we know that it did in fact not safely shutdown the drive before, when I
thought it's just the drive cache flushing that failed. So the drive is doing
recovery, internally, upon laptop poweron which is why it doesn't identify
itself in time but only on next ctrl+alt+del boot. (see comment #1)
