Subject: Firmware errors and warnings with Centrino Advanced-N 6205
Hi,
I'm repeatedly getting firmware errors and warnings on my Centrino 6205 WiFi
card with Linux 3.1. These warnings keep filling the logs at a rate that is
not funny. Any idea how to fix this issue or at least rate-limit those
messages?
Cheers,
- Udo
