Only an "occasional" bad deal? Lockup doesn't happen every time.
I'll make this a "watch" item for the time being. I'd apologize for the
noise, but I never saw this happen prior to running the 4.14 kernel.
Maybe was just lucky up until now :-(.

Running a 32-bit SMP kernel per "uname -a" output below:

Linux gherkin 4.14.0 #1 SMP PREEMPT Thu Nov 16 23:34:38 CST 2017 i686 Intel(R) Core(TM) i7-2600S CPU @ 2.80GHz GenuineIntel GNU/Linux

The i7-2600S has four hyperthreaded cores (/proc/cpuinfo shows 8 CPUs).
