Vitaly, have you really run into cases where 2G upper limit is a concern.
What is the configuration you have, how much memory it has and how much
memory are you planning to reserve for kdump kernel?
A good question.
We have observed that on a machine which has 66G memory, when we do
crashkernel=1G@4G, kexec failed to load the crash kernel, but the memory
reservation _did_ succeed.
Thanks.
