Miller It's quite possible that this fixes it, especially since the version in Ubuntu's bug report came out the day before your fix went in :) However, I don't really get why it's crashing in the first place. Without your patch, if the device is renamed the proc entry just keeps the original name. When it goes down it should still get removed correctly. Could you explain this in a bit more detail?
