fwiw, this bug went away once i upgraded the BIOS of the machine.
the old bios was:
TYBYT10H.86A.0019.2014.0327.1516
The new bios is:
TYBYT10H.86A.0061.2017.1011.1904
After this upgrade, new kernels boot just fine.
The bios file i installed was TY10H0061.bio, with sha256
2b841a072ce65b1b73cb494b7d291e11c245b7373c601559f5547981a10c9543
This apparently also improved the onboard DRAM controller so that it's
now operating at 1600MHz (0.6 ns) instead of 1066MHz (0.9 ns).
So, i think this was a hardware problem, and not a problem with the
kernel, so i'm closing this bug report. I don't know why the newer
kernels had the problem with this hardware but older ones didn't. ah well.
hope this info helps,
