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. -- Connection droped or system crash whean trying to transfer large files over wi-fi https://bugs.launchpad.net/bugs/389891 You received this bug notification because you are a member of Ubuntu Bugs, which is a direct subscriber. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
