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). https://bugs.launchpad.net/ubuntu/+source/linux/+bug/209346 2009/5/12 Amit Kucheria
