In fact, I liked 3.15 enough to base glibc on its headers. Here's hoping that I can reproduce the issue on a 3.10-based utility partition. [Somewhere out there is a Murphy's Law of glibc Upgrades that describes this situation perfectly.] Should it shed any extra light, here's the ftrace-dump-enabled dmesg from the most recent crash (mkdir/rm test), after my closing. Thanks! A Pentium III can bisect kernels only so quickly, so this will take some time.
