Hello All,
Attached is some information which is always reported on /var/log/messages since I started
to use FC6. I have no clue at all about the impact though as everthing seems to be working
normally.
I have posted this issue on Fedora-test-list and suggested to report it here. It was said
that this is an indication of a bug in zaptel driver. Is it not?
Cheers,
Anto
