Well, indeed. ;)

You should throw your broken hw away, if it causes harmful interference.
It's as simple as that. Problem solved. :)

Hardware simply often _is_ crap and causes harmful interference.
One example being an S3 video card which caused a parport extender card
to output extremely crappy signals. I simply bought a new video adapter
and all interference problems disappeared.
Often such interference doesn't matter. I bet the parport adapter still
worked with most common parport devices. But I had a milling machine connected
to it which moved a tiny bit on each interference storm. So I could move the 
joints
with glxgears. ;)

So I can certainly imagine that interference can break a wireless adapter
completely. In fact, I do own a motherboard where 90% of broadcom wireless NICs
fail to work on. It clearly is caused by interference, because they work fine
if I put a shielding extender between the board and the NIC.

b43 on via cpu

2009-02-25 Thread Francesco Gringoli 
Hello everyone,

I tried without success to run b43 on a via (cpu) pc and I got a very  
strange behavior. Everything seems to work fine for a random time  
going from 60s to a multiple of 60s. Then dmesg reports that a direct  
probe failed and that b43 lost the connection to the AP.

I tried both ubuntu and slackware (thinking it could be due to ubuntu  
network manager) and always with kernel 2.6.29-rc2-wl, the same I'm  
using on all my development platforms (and I never got problems with).  
I had the same problem with a number of BCM adapters so it was not due  
to the wifi adapters.

I took the same hardware and same kernel to other platforms not via  
based and the problem disappeared: the only difference was the VIA cpu  
instead of anyone else not VIA.

If it can worth I can report more details on the VIA architecture I  
was using, but I don't know if there is anyone who cares about :-)

Cheers,
-FG
