Description Chris Adams 2006-09-14 19:15:58 UTC 
When trying to help a cow-orker load the current rawhide tree on an iBook G4,
yaboot gives "method 'load' failed 00000300" while loading the ramdisk from the
network.  The FC5 installer will load okay from the network.

After Googling, it appears to be related to the size of the image.  I stripped
out some unneeded modules (SCSI device modules for Adaptec and Qlogic), the
image is small enough to work.

Either yaboot needs to use a larger buffer or the ramdisk image needs to be
slimmed down by default.

Just a larger buffer doesn't fix it here, we need to rework the mmap
implementation for larger than the current limit.  Apple firmware deals with
slightly larger than 6M but IBM will fail past the current limit.  I have some
patches I'm looking at for this for yaboot HEAD.

I'm resolving this as UPSTREAM because it really is an upstream source problem.
