Hi there,
I use GNU/Linux Debian (Lenny) and I'm getting the message below endlessly even after finished loading the boot:

$dmesg
.
..

p.s: I have no USB device attached to my laptop.

So, when I toggle tty to another without graphical environment, I simply can not use it 'cause this annoying message keeps showing up making impossible to use shell interface.

Someone knows what it is about or how I can fix it?

I have got the same problem, it's really annoying.
Any ideal?

can ur find anything significant regarding this in /var/log/messages

i got it to stop after I finally found the wireless driver source (from the official Broadcom website) and compiled it to my current kernel, so that the wireless started working (without using ndiswrapper).

Now I'm not using Debian anymore, and it didn't happen on OpenSuse (the one I'm using).

Maybe you have any device that is not properly recognized/installed , then it happens.

I'm using an Acer Aspire One with the ATH5K driver module, so no ndiswrapper...

It happens for about 30 minutes after I turn it on. then it said "choping to config(s) (I think, that is from memory)

So still no fix, anyone have any ideas?

Thanks
