I would guess (given the distro change is the trigger) that you've

and in ways it didn't use to. That would fit the fact that something
similarly broken has apparently also appeared in the Fedora user space
bootup.

And we (suse) have a report for enterprise, that says ModemManager
causes a similar issue. Could you perhaps check whether you have that
thing installed?

thanks,

Yep. ModemManager-0.5-3.1.3.i586

And what happens if you remove that?


It seems to fix my problem. Thanks for stepping in. I was about to take this to the SuSE-e list.
Anything else ya need, let me know.
