Rick, Does this error happen with specific memory configuration? Or is more generic? I have lost track if in this email thread we are still talking about error related to the change in memory allocation I made to use memory below kernel? Also are you using the latest master or 0.53 specifically?
I thought we are talking about error when one passes 1.01 or 1.02 GB as memory size. Is it true? I understand we have found slew of possible other bugs.
