It was the regular -tip test cycle/iteration: booting the kernel and
building the next new (random) kernel on that system, then booting that
(random) kernel ... etc. The warning occured some time after bootup, so it
probably triggered during the building of the next kernel. (one kernel
build takes about 1-2 minutes to finish)

The problem was not reproducible - i tried the same config once more and
it didnt produce the bug. (this system has no known hardware flukes)
