From: Miles Lane To: "Rafael J. Wysocki" Cc: Linux Kernel Mailing List , Greg Kroah-Hartman , David Brownell Content-Type: text/plain; charset=ISO-8859-1 Content-Transfer-Encoding: 7bit Sender: linux-kernel-owner@vger.kernel.org List-ID: X-Mailing-List: linux-kernel@vger.kernel.org This does seem to be a regression. I just checked with Ubuntu Jaunty running 2.6.28-6-generic. The USB host and USB flash drives resume perfectly with this setup. I tested having Nautilus windows open for both drives, suspending and resuming. After resuming, I was able to work with the folders and files in those Nautilus windows.
