I was too fast to post previous message after some 10 minutes of testing. However a recent driver upgrade from 3.13.0-45-generic to 3.13.0-46-generic (with the same firmware) has apparently solved this issue for me. At least, dmesg does not contain such errors after an hour of heavy network usage and the network seems to be stable. The version numbers above are the ones reported by lshw for my wifi card.
