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.
