Hello!

I am running current on i686 on a Thinkpad X40.

lsmem works on other systems, but not on this.

I read that it was originally created for s390, so my question is: Is
that supposed to run on i686?

It works on x86_64 (amd64).

probably not. even on 15.0, not likely lsmem issue, but later kernel
issue. also does not exist on arm. No idea when they broke it, must be
years ago.

It works on my x86_64 Intel(R) Core(TM) i5-4590.

Thanks for telling me about this interesting command. I wonder what
practical uses it has?

Getting information about installed memory.

Maybe it is historical for s390.
I haven't had such a system, but maybe they have detachable memory, so
modules can be inserted and removed while the system is running.
