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

lspci -vv
Comment 2 Nikolay Amiantov 2014-01-26 20:20:12 UTC 
Rised priority since this looks very bad, and network works very unstable from boot.
Comment 3 Nikolay Amiantov 2014-01-26 22:36:35 UTC 
I've worked for some time, and connection is interrupted from time to time, with similar errors showing up. I can reconnect after that.

The patch will take some to go upstream though...
