How about these kernel options ?
memmap=exactmap [KNL,IA-32] Enable setting of an exact E820 memory map, as specified by the user. Such memmap=exactmap lines can beconstructed based on BIOS output or other requirements. See the memmap=nn@ss option description.
memmap=nn[KMG]$ss[KMG] [KNL,ACPI] Mark specific memory as reserved. Region of memory to be used, from ss to ss+nn.I used memmap=3K$637K to avoid the 3K segment just below 640K (which my BIOS diagnostics told me was reserved), with no luck. I bumped that up to memmap=30K$610K (lots of padding), also without luck.
Similarly, I have tried: memmap=240M@16M (no luck) And mem=240M@16M ( no luck)
as there seems to be some varying opinions on the 'net as to which of those is correct syntax.
There are not varying opinions. Using @ (instead of $) is a valid syntax if you want to _force_ the kernel to use that region :)
Of course, I might be wrong about the base cause in which case none of this is relevant ;-)
Can't help you there :)
