dmesg

This is with latest kernel from linus git tree on a CAPE VERDE card.
When the errors appears I get screen corruption when scrolling in a
browser/file-manager and missing/changed letters in a terminal.

A bisect led to the commit 161ab658a611df14fb0365b7b70a8c5fed3e4870 and
reverting it on master makes everything work normal again.</pre>
