You're probably using a kernel compiled with SMP support either don't
|
|
use SMP or try here:

Right, I haven't got a concrete answer here but I couldn't find it anywhere on the internet so here goes. I found this error come up when I recompiled my kernel once. It did it the first time but I forgot how to fix it. A combination of things fixed it for me:

As I said I can't be sure about this one but it worked for me. </P

When you pick up the phone there are strange noises present, more over
|

the use of the phone line causes the internet to disconnect.</P

You seem to have something which I thing is called cross-frequency. The
|
|
ADSL modem works by sending data down the unused frequencies of you
|
|
copper phone line. If the hardware is set up so the ADSL and phone
|
|
ranges overlap the two can receive each other's data. Ring BTO Customer
|
|
Support and they should be able to help.</P
