Re: 3.0-rc1: powerpc hangs at Kernel virtual memory layout

It -looks- to me that something goes wrong in the tty code when a large

the workqueue / ldisk flush code. I've just sent an initial report to
Alan Cox about it and am currently bisecting it.

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.
