another boot hang (not the jffs2 one)

[Daniel Drake]

I'm seeing a hang during early boot of recent F11-XO images. Right now I
have reproduced on freshly-reflashed 20090528 and 20090525, on 2
different XOs. It is not the "Unknown filesystem jffs2" hang or the
"Creating devices" hang. It is much earlier, before the kernel has even
kicked the framebuffer.

At the point of the hang, the output on screen is:
Boot device: /nandflash:.......
Loading ramdisk image from nand:\boot\initrd0.img ...

(this screen is from the OpenFirmware boot process, the screen
background is still grey, the Linux kernel does not appear to have
become alive at all)

It hangs at this point, with no extra output on serial console, and is
unresponsive to OFW frame key for interruption.

Is anyone else seeing this? (please don't confuse this with other boot
hangs, where the screen contents are different)
