The unified-stable git tree at: git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-2.6-stable.git appears to be broken. No updates in 8 days, now. I wondered if it changed URL due to the switch to 3.x and tried removing -2.6 or replacing it with a 3, but git.kernel.org terminates the connection when I try that, so apparently it doesn't know those repo names, only the old linux-2.6-stable.git name. So it appears to be server-side update script related tho likely still kernel 3.x change related as well.
