Kernel 3.5 and p54usb = wifi disconnections.

My wifi device:

Bus 002 Device 002: ID 1435:0427 Wistron NeWeb UR054g 802.11g Wireless Adapter [Intersil ISL3887]

Always worked fine under linux. Since upgrading to 3.5 kernel i have random disconnections. I am using networkmanager and systemd. Link doesn't fall but i lost my internet during 5-10 seconds.

wlan0: deauthenticated from 23:66:b2:b5:27:4e (Reason: 7)
