[Lucid] [Patch 0/3] SRU: Fix usbdux driver timeout and lockups

[Leann Ogasawara]

Hi All,

https://bugs.edge.launchpad.net/ubuntu/+source/linux/+bug/483343

SRU Justification/Impact:

Per the request of the usbdux maintainer, the following patches resolve
a usbdux driver timeout and lockup.  All three patches have landed in
2.6.33 upstream.  Please note that this set of patches depend on the
patch to fix bug 563436 (ie re-enable comedi drivers).  I recognize we
are frozen for the upcoming release so please consider this for the
first Lucid Stable Release Update.

TEST CASE: 

I've built a test kernel with the upstream patches applied.  I've
received confirmation from the bug reporter (usbdux maintainer) that
this indeed resolves the timeout and lockup.
