Hurd doesn't boot with 1024 Mb RAM

[Gerardo Pirla Diaz]

Hi James,

First, many thanks for your help.

The problem was the ammount of memory, but uppermem doesn't work !!!

I've tried:

        uppermem=131072
        root (hd1,1)
        kernel .............

And it causes a kernel panic !!!

Pulling out a ram stick, GNU/Hurd boots OK !!!

I've tried the grubs uppermem parameter with an L4/Fiasco kernel,
and grub works fine (is documented L4/Fiasco that doesn't boot
with more than 256 Mb)

Maybe a mach/hurd BUG ??

There is no reason to physically remove ram from a machine.  GRUB has an
option, uppermem, that limits the amount of RAM the os booting from GRUB
sees.
