Just for sake of curiosity I tried Peter Holm's stress2 test suite, which
compiles without issue on the RPi3 when svn'd from his website.
After running for not quite three hours the following appeared on
the console:

The thing which most struck me was lines such as
Mar 7 18:19:27 www kernel: t csmcdh edt_hyri2e lpdid
in which the timestamp and origin of the message is undamaged, but
the content is thoroughly mangled. Does it provide any help in localizing
within the system what is out of sorts?
