Comment 29 for bug 275359

yes , this issue exists with the most recent Jaunty Jackalope 9.04 release

I have that issue with:

kernel 2.6.28-11-generic
Intel Corporation PRO/Wireless 5300 AGN [Shiloh] Network Connection

I also think that this issue could be related to a firmware bug ( I verify a
corruption of ext3 if I use wifi connection).
