Bzzz, thank you for reporting this bug and helping make Ubuntu better.
If you could also please test the latest upstream kernel available that
would be great. It will allow additional upstream developers to examine
the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once
you've tested the upstream kernel, please remove the 'needs-upstream-
testing' tag. This can be done by clicking on the yellow pencil icon
next to the tag located at the bottom of the bug description and
deleting the 'needs-upstream-testing' text. Please let us know your
results.
Thanks in advance.
** 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...
