OK, ps3_defconfig does not need an initrd.

OK, this reboot hang is a different problem.  I'll put it on the todo
list.  Please send me the .config file if you can.

OK, could you please try with with ps3-linux.git and ps3_defconfig?
Let me know the checkout revision number when you report.

OK, my guess is a problem in the ps3 ehci HCD (drivers/usb/host/ehci-ps3.c),
or a hardware errata.  

Could you try with CONFIG_PM=n.
