Hi,

“Failed to alloc highmem for initrds” is what you see from the linux
kernel? If not what is the ipxe.org error url that is show together with
that message?

Which kernel version does Suse 12.1  use?, Could it be a known bug in that
kernel as seen here:
http://forum.ipxe.org/showthread.php?tid=7756&pid=11699#pid11699  (I can
never find another nice post that mcb30 made about the issue with a link to
patch for a fix that was applied to the linux kernel tree)

This is probably not a size issue, but rather random corruption in the
linux kernel when loading the initrd.
