[Comm] сеть перестает нормально работать: iwlwifi: fail to flush all tx fifo queues

[Maks Re]

Здравствуйте,


как  то "не удобно" работает беспроводная сеть... 

подскажете в чем дело, как исправить?
может какое старое ядро есть когда это точно работало? я не помню, было ли такое вообще...

система: железка thinkpad x220 
OS: altlinux p7 branch x64
$ uname -a
Linux horse.localdomain 3.12.17-std-def-alt1 #1 SMP Tue Apr 8 10:12:59 UTC 2014 x86_64 GNU/Linux


кажется что-то с прошивкой? судя по сообщениям в сети...
