Ok, this bug needs some clarifications: Neal, the original poster [1], refers to a different problem than Julien[2]. The Julien problem looks rooted in the kernel and was reported in a different bug [3].
Anibal, probably the best path of action is to recheck with Neal if his problem is still there and close this issue, since it is 5 year old, in Debian 6 (Squeeze), not maintained anymore.
