Hi,
I'm testing 2.6.35-rc4+, I have problem that warning is spamming dmesg
when I have my wifi on. Actual problem caused y that problem is that I
can't scan/connect to any network with 2.6.35.
When I looked the code in warning it might be related to problem that
my wifi reports all signal strength to be 175 or 178 (if I remember
correctly). I'm now using 2.6.35 so I can't check the reported values
from scan results.
