I have found the production Fedora 15 kernel, posted under updates .  I 
had forgotten that Fedora is a perpetual beta distribution, and a (more 
or less stable) kernel (not a rc) would be in updates.  That said, I 
have the following RPMs available:

kernel-2.6.38.8-32.el6.x86_64.rpm
kernel-devel-2.6.38.8-32.el6.x86_64.rpm

that seem fully to function (again, Nvidia latest 
NVIDIA-Linux-x86_64-275.09.07.run and VirtualBox modules build and seem 
to work).  I will report any crashes/panics or other anomalies to the SL 
list.

Does anyone have a possible date for when the production stock SL6 
(RHEL6) kernel will be updated (backported) to provide the full USB 3 
support of the 2.6.38 series?
