There also has been a lot of fixes by Lukas Wunner to the DMA engine driver.

It even stopped logging over the network - only the serial console shows the message: Linux version 4.4.176-1.g755499f-default (geeko@buildhost) (gcc version 4.8.5 (SUSE Linux) ) .... ( 7/526) Installing: info2html-2.0-223.1.noarch .........................[done] ( 8/526) Installing: libX11-data-1.6.3-10.3.1.noarch ...............<89%>===[|][ 664.670582] sdhost-bcm2835 3f202000.sdhost: ti. [ 674.750501] sdhost-bcm2835 3f202000.sdhost: timeout waiting for hardware interrupt. So at least on 4.4 kernel this does not help. Thanks Michal
