3.13-rc8 is out, and 3.13 Final should be out in about a weeks time – or so..
Changes are here: http://email@example.com/msg568052.html
Same comments apply for VMware and NVIDIA drivers on x86_64 as for -rc7, and the DreamPlug (armv5tel) still gives the usual batch of mvsdio f1090000.mvsdio: unhandled interrupt status=0x0810 en=0x0100 pio=0 errors on boot, but otherwise runs OK, without any further error messages. If this persists for 3.13 Final, I may post details to the ARM Kernel mailing list, after further investigation..
