dmesg

There is lots of firmware errors dumping into dmesg once I try to connect to my network. Surprisingly, WLAN works even with this (though there was time when it wasn't), but this definitely isn't right.

Steps to reproduce:
1. Start connecting to some network (I use NetworkManager)
2. Check dmesg

Rised priority since this looks very bad, and network works very unstable from boot.

I've worked for some time, and connection is interrupted from time to time, with similar errors showing up. I can reconnect after that.
