Hmmm, think I was getting the same effect with emplode the other night (using ethernet). Was changing things with emplode, and was getting quite a few lockups. Didn't investigate thoroughly at the time to check that it was only happening after an emplode sync though - will try and remember to have a look next time I am at work
