>Description:
I own a K7S5a mainboard and I get such a message about once per 10
minutes on the console:

ohci1: 3 scheduling overruns
ohci0: 1 scheduling overruns
ohci1: 1 scheduling overruns
ohci0: 1 scheduling overruns
ohci1: 1 scheduling overruns
[...]
etc.

I don't have anything attached to the USB ports. So I don't even know if
they work. Should I worry about this message? If not, shouldn't the
message be suppressed?

Here are some lines from /var/run/dmesg.boot:
