Technically I think there were three generations of 64-bit system
that shipped with this, not just 32-bit. I see that end of support
life for the x3650 M1 server was in 2018, which is still a long time
ago, but not quite as old as you make it sound. As far as I can tell,
SLES12-LTS still supports those servers until next year and runs
the userspace for ibmasm, but obviously won't update their kernels.
