False alarm, sort of.  It seems that sometimes the automatic location 
selection mechanism is picking an invalid location.  If I specify the 
location manually it seems to work okay.  I'm using the default 
settings, so adapter->fdir_pballoc is 1.

I'll add some instrumentation, see what location it's trying to use.
