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.
