Well I know running a 64 bit kernel on that model, does see 16GB ram.
But I was doing that with no LPAR or anything else, just Debian installed

understanding that people might do that).

So either you somehow installed a 32 bit kernel, or you have an LPAR or
something else restricting your memory size.

No LPAR or VM, running just "bare metal". I had AIX installed previously and it recognized 16Gb.

Seems like a config issue? Wouldn't a 32 bit kernel see the 32 bit limit, under 4Gb?
