Actually, it's not that sporadic, simply doing:

	$ bitbake -c clean core-image-minimal
	$ bitbake core-image-minimal

shows the taskhash mismatch error repeatedly:

	core-image-minimal-1.0-r0 do_image_rpi_sdimg: Taskhash mismatch 536a3bcf4ac29225841c369636b533ff versus 8fadff5d0ef51aa648ed359d5dd7f944

Or I could just perform clean builds in succession.

The reported hashes are always the same: from 536a3bc... to 8fadff5... This
mismatch happens _during_ the build, not between two subsequent builds.

I'm not sure how to compare hashes, every subsequent build produces the same
two hashes. The build always ends with:

	tmp-glibc/stamps/raspberrypi2-oe-linux-gnueabi/core-image-minimal/1.0-r0.do_image_rpi_sdimg.8fadff5d0ef51aa648ed359d5dd7f944
	tmp-glibc/stamps/raspberrypi2-oe-linux-gnueabi/core-image-minimal/1.0-r0.do_image_rpi_sdimg.sigdata.8fadff5d0ef51aa648ed359d5dd7f944

so a "bitbake-diffsigs -t ..." will always be blank.
