It's c3b1b1cbf002e65a3cabd479e68b5f35886a26db: 'ramfs: add support for 
"mode=" mount option'.

And I checked. Reverting it at the tip fixes it. So no random timing 
fluctuations.

So that commit causes some random SLAB corruption, that then (depending 
apparently on luck) may or may not crash in some odd random places later.
