>Description:
        Some time sources after 2014-07-31 the RPI started to fail to work on 
ld0 with I/O error an any transfer about 8-20h after boot.
>How-To-Repeat:
        Use source somewhat after 2014-07-31 (short before 7 branch). build an 
RPI system (evbarm/earmv6hf) and run for about 12-20h. Watch I/O on ld0 fail 
rendering the system unusable.

>Fix:
        revert back to source around 2017-07-31 or before. (so HW is probably 
not at fault)
