Can confirm the bug (not present in Ubuntu 10.04, not tested in 10.10 but present in 11.04) with a Realtek chip (see attached output from lspci -v) and the workaround by Adam Bolte. But it seems like my system is removing the realtek driver during restart and loads the buggy driver again. At least the bug is occuring after restart and after reinstalling the realtek driver its gone again. Would be perfect if somebody could fix the ubuntu driver or find a way to permanently install the realtek driver (although the bug wouldnt be fixed by that ;-))
