After fighting some time with WD-EARS green disk errors, those seem to get away by simply changing the BIOS ata mode from native-ata into AHCI. Recently during system idle state the ata bug has triggered. Suspected WD-green's again, but surprisingly this time it was related to GOODRAM ssd. I admit this drive is attached only for windows intallation, has been in the idle state and wasnt mounted when the bug occured.

Still happens with latest mainline generic kernel 4.15.3-1 in the same circumstances. SSD disk related to the affected ata port was unmounted during exception. The error in journal is EXACTLY the same.
