It is strange but this workaround doesn't seem to help me booting Koelsch
reference kernel with NFS root: it still crashes due to imprecise external
abort once the userland starts. Only the actual drivers/sh/ fixing series by
Ben/Geert helps with booting further. I therefore would like to have it merged
by Simon the sooner the better...
WBR, Sergei
