** Description changed: I noticed a significant worse performance of my USB 3.0 Expresscard when using 3.2.0-22-generic compared to the older 3.2.0-21-generic. Controller is a 05:00.0 USB controller: NEC Corporation uPD720200 USB 3.0 Host Controller (rev 03) + a Corsair Flash Voyager GT 3.0 32GB I tried it four times each, and results were the same every time. Shutting down or just rebooting the machine to the other kernel version does not make any difference - it clearly has something to to with the kernel itself. Boot options where the same on both cases, I tried it with the USB storage attached at boot and also connecting it later. Please note the attached screens of the benchmark feature of Disk Utility (palimpsest). Oh, and don't wonder why I'm reporting sound problems. I used ubuntu-bug file this bug and choosing the right menu item leads to sound check. Maybe bug #558824 needs some attention, too...
