Also make sure you don't have any stale stuff from previous versions in /etc/udev
Yes, make sure you have not modified the udev rules to do something else. Please post your version of udev, as I can not duplicate this here either.
I had not modified serial port related configuration. Only added an 'additionnal' script, and relead the daemon in local.start. I removed all symlinks, and reboot was OK. Took time because comp had night work to do, and could not reboot earlier.
reopen to clseo afterward
definite close: sfix was: remove all symlinks and reboot.
