OK.
I tried the watchpoint patch mjg@ sent; as noted in my response to him,
I did not see the problem recur when I booted the resulting kernel.
And given your observation, as well as that I've updated 4 other
stable/9 systems (sources at r241801 for 3 of them; at r241786 for the
other), none of which exhibited the problem, I suspect that something is
remarkably sensitive to the storage layout.
Hmmm...
Peace,
