https://bugzilla.kernel.org/show_bug.cgi?id=151631 --- Comment #3 from icanrealizeum <icanrealizeum+bugzillakernelorg@xxxxxxxxx> --- 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 screenshot: https://i.imgur.com/2yvAMSR.jpg 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.
