This was the "tty vs workqueue oddities" thread, right? FWIW, 55db4c64eddf37 ("Revert "tty: make receive_buf() return the amout of bytes received"") seems to have fixed it on this powerpc machine as well.
With your "ssb: pci: Don't call PCIe specific workarounds on PCI cores" patch applied, powerpc32 seems to be quite happy with 3.0-rc1+
Thanks, Christian. -- BOFH excuse #382:
Someone was smoking in the computer room and set off the halon systems.
