Details, details :-)  Coincidentaly, I discovered that running without
making first causes confusing output (everything skips).

Unless I omit waffle, it insists on using gles (not available on 12.04?),
so build fails.

Yes indeed.  Locks solid after test 72 or so.   This is an old 8 core
xeon box, fwiw.
Interesting lines from summary:
spec/arb_shader_texture_image_samples/compiler/fs-image-samples.frag: fail
spec/arb_gpu_shader5/execution/sampler_array_indexing/fs-simple-texture-size:
incomplete
Nothing in dmesg.
I see the incomplete test is only two months old, so maybe this doesn't show
up in online summaries of results for this five-year-old card...

In this case, the quick tests live up to their name :-)

Good point.  I may have to resort to that if the stability problems continue.

This morning's order of business: while raid rebuilds again on the
first machine :-)
run tests on two 16.04 machines: one more old 8 core Xeon with a W600,
and one new Sky Lake integrated graphics system.

p.s. here's the result from the one failed test (that didn't crash),
for completeness.
