Maybe a broken RAM controller, i.e. the content of the initrd
"disappears" after it has been loaded. Someone just reported that a
Firmware/BIOS update on his computer solved a similar problem. It may
also be possible to use the mem= boot option, as described in
/usr/src/linux/Documentation/kernel-parameters.txt:
mem=exactmap [KNL,BOOT,IA-32] enable setting of an exact
e820 memory map, as specified by the user.
Such mem=exactmap lines can be constructed
based on BIOS output or other requirements.
mem=nn[KMG] [KNL,BOOT] force use of a specific amount of
memory; to be used when the kernel is not able
to see the whole system memory or for test.
mem=nn[KMG]@ss[KMG]
[KNL,BOOT] Force usage of a specific region of
memory
Region of memory to be used, from ss to ss+nn.
mem=nn[KMG]#ss[KMG]
[KNL,BOOT,ACPI] Mark specific memory as ACPI
data.
Region of memory to be used, from ss to ss+nn.
mem=nn[KMG]$ss[KMG]
[KNL,BOOT,ACPI] Mark specific memory as
reserved.
Region of memory to be used, from ss to ss+nn.
