Because someone said that there would be no logging of unerlying ATA errors without verbose, I rebooted with verbose and tried the same make -j4 again... and here is the relatively similar core.txt.5 https://uk.eicat.ca/owncloud/public.php?service=3Dfiles&t=3Dd99648ef5876b91= c5957148445e60c87 Looking at it, gmirror is dropping the same error and the underlying hardware is not causing the error...
