But if I go past 2GB, I get random crashes during all builds (world, kernel, port). Is there anything I can do to try to debug this or are there any tricks to either debug or solve this? Oh, and is there any support at all for finding out the 3ware status? It would be nice to know if a drive fails but 3dm is marked i386 only. /\/\ \/\/
