[gentoo-user] Disable the access to a defined memory area

[Pongracz Istvan]

Hi,

One of my partners has a problem in an existing motherboard.

There are physical memory regions, which regions are buggy.
I do not know, the memory module itself, or them motherboard, but if the
kernel want to access to these region, it crashes.

I would like to know, is there a solution to make a memory hole, which
will be never addressed?

The situation is similar, when the HDD has bad sectors and I cover them
with a never-used-partition or file.

I googled a while, before I wrote this email, but I have no result yet.

Thank you,
István

I think a boot parameter of the form
reserve=0xff48ffff,0x870000
should do the trick.

Thank you very much!
reserve seems for io regions, but memmap=nn$ss seems ok.

Thank you again, you started me to the right direction.

You should really replace the broken components. However, google 
for "badram".
