..
I had a strange thing happen with 2.6.24[.0] the other day.
My bluetooth serial dongles stopped working.
Unloading/reloading modules and daemons had no effect.
A system reboot cured it (for now).
That's the first time I've had unfixable bluetooth trouble, well, ever I suppose.
Just another useless data tidbit on 2.6.24.
