Re: Atari 4 MiB kernel limit

Funny enough I currently got problems with load the kernel on Arrakis, an A3000, although I already reduced the memory from 128M down to 64M with no success. 
It ran wirh the same setup for months now, until I shut it down for cleaning today.

That's a very good question ;-)

The 4 MiB limit only applies to early startup, in arch/m68k/kernel/head.S.
Initrd is accessed later, in arch/m68k/kernel/setup_mm.c, so I'd expect it to
not fall under the limit.

Of course, better try it to be sure ;-)

In personal conversations with technical people, I call myself a hacker. But
when I'm talking to journalists I just say "programmer" or something like that.
