Hi, I have a Marvell Kirkwood 88F6281 device, which I'm trying to get running with FreeBSD. It's in a D-link model "DNS 325", which has 256MB RAM. With FreeBSD 8.3, I found a hang on boot using the default DB-88F6XXX config. I found PHYSMEM_SIZE=0x20000000 hardcoded in sys/arm/mv/kirkwood/std.db88f6xxx which I presume means 512MB RAM - so I changed this to 0x10000000 and then 8.3 booted fine. Now I'm trying 9.0 (primarily because I'm interested in the recent NAND work) and I see the PHYSMEM_SIZE option was removed by commit [210249]: http://lists.freebsd.org/pipermail/svn-src-head/2010-July/018727.html The default 9.0 DB-88F6XXX kernel hangs in exactly the same way as 8.3's did for me: ## Starting application at 0x00900000 ... dtbp = 0xc0c04408 Copyright (c) 1992-2012 The FreeBSD Project.

Is there a way I can hardcode the physical memory size which would be equivalent to 8.3's PHYSMEM_SIZE option? Is is there a better way to solve this, and have the memory size found automatically? Thank you, -- Kate
