[Bug 219868] [NEW] Boot fails with "initrd extends beyond end of memory" after upgrade to Hardy

Public bug reported:

I have an Olivetti Netstrada 7000 with 4 200MHz Intel Pentium Pro
processors and 256MB of RAM which was running the server version of
Feisty.  I upgraded it to Gutsy with "sudo do-release-upgrade" and it
worked fine, but when I then upgraded to Hardy with "sudo do-release-
upgrade -d" I found it wouldn't boot.

The boot error is:

initrd extends beyond end of memory (0x0ffef173 > ox01000000)
ACPI: no DMI BIOS year, acpi=force is required to enable ACPI
Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block (0,0)

So it's complaining that 256MB > 16MB, which whilst being technically
correct is not very useful.

The ACPI message is harmless, I get the same with the Gutsy kernel that
still remains and (fortunately) still works!

I've attached the dmesg output from the Gutsy kernel and will attempt
booting with mem=256M.
