[Bug 389891] Re: Connection droped or system crash whean trying to transfer large files over wi-fi

[Mikael Hjelm]

I seem to be affected by this problem also.
When it happens i see either of two error messages in dmesg: 
ath5k phy0: can't alloc skbuff of size 2559 
and
ath5k phy0: noise floor calibration timeout .....

The first error message lead me to believe that there might be an issue with running out of memory. 
Running top when downloading a large file over WLAN i can see that the memory is reducing rapidly. 
Then when the memory is almost out top freezes for a while and all of a sudden there is a large chunk of memory available again, that time the download didn't fail but i beleive that if the timing is off then it might.

So my assumption is that a high speed wlan download, the problem is more
severe when loading large chunks of data from local server or streaming
video from local server, combined with a slow disk write speed and small
RAM is the problem here.
