 -rc6 has been released, and kernel.org is still down. I cloned Linus's github repo so as not to disturb my kernel.org repo (yes I know I could have pulled from the github repo, and with a few other magic git incantations resulted in the same thing...maybe...). There have been some OMAP4 related changes, but applying the same patches as -rc4, a working kernel as described below is the result.

 -rc5 has been released, and kernel.org is still sort of sick. Not to worry, Linus has a github repository that you can pull from (if you dare ;>),
 see https://lkml.org/lkml/2011/9/4/92 for details. From the changelog, it doesn't look like any omap4 or PandaBoard related changes, so we'll wait a bit to see if kernel.org recovers after the holiday.
