[Bug 189269] Re: CONFIG_HIMEM4G does not allow 4gb of ram in kernel

[Leann Ogasawara]

Note that enabling CONFIG_HIGHMEM64G also enables CONFIG_X86_PAE by
default.  This will most likely not be enabled by default until the
known implications of having CONFIG_X86_PAE enabled can be determined.
As a workaround, can you try using the following kernel parameter to see
if it helps:

ramdisk_size=[RAM] Sizes of RAM disks in kilobytes See
Documentation/ramdisk.txt.

It was also mentioned that this was fixed upstream.  I'm curious if
anyone would be willing to test with the the Intrepid Ibex 8.10 kernel?
It was most recently rebased with the upstream 2.6.25 kernel (which
contains the patch you've referenced) and is currently available in the
following PPA:

https://edge.launchpad.net/~kernel-ppa/+archive

If you are not familiar with how to install packages from a PPA
basically do the following . . .

Create the file /etc/apt/sources.list.d/kernel-ppa.list to include the
following two lines:

deb http://ppa.launchpad.net/kernel-ppa/ubuntu hardy main
deb-src http://ppa.launchpad.net/kernel-ppa/ubuntu hardy main

Then run the command:\n\nsudo apt-get update\n\nYou should then be able
to install the linux-image-2.6.25 kernel package. After you've finished
testing you can remove the kernel-ppa.list file and run 'sudo apt-get
update' once more. Please let us know your results. Thanks.
