I have seen the same effect that Rob describes, in two separate circumstances. One was when I was running Linux native on a P/390, where I had to tell Linux I had 124MB instead of 128MB in order to IPL around the 128kB HSA on these machines (this was a well-documented process that those of us who ran -- indeed, still run -- Linux natively on a 7490 had to do to make it work). The other was when I was trying to fine-tune storage allocation to a router guest -- I documented my experiences in my "Porting LEAF to zSeries" redpaper. Maybe the kernel does not "round down" the storage size, but *something* definitely causes Linux to see storage in multiples of 4MB. Cheers, Vic
