I have a laptop with some corrupted ram addresses, so I'm trying to use memmap to reserve them before linux boots up.
I have been trying to use
memmap=10M$1024M as a kernel boot option, but linux crashes (with no errors) and restarts. If I use a different syntax for memmap like
memmap=1023M@0M it boots fine.
Do I have to specify a certain size block to reserve or could my kernel version not support reserving memory with memmap?
Maybe I'm better off using
memmap=exactmap, and if so, could somebody point me to a good faq on how to use it?
