Timeout while waiting for nf to load

[Dmitry Kolosov]

Please help!
The problem: while watching a movie over NFS over wireless, transmiting and 
receiving stops for about 10-20 seconds every 5-10 minutes, and i see this in 
messages:

Other wireless operations runs smoothly, without any glitches. I think it 
happens only on huge wireless load.
