Hi,

I just noticed PR 24978 was closed four days ago because the problem
("The boot process stops quickly after some addresses display and PC
reboots" when using large MEMORY_DISK_ROOT_SIZE) was fixed; I updated
my sources and tried again, but without success: now I can't even use
small (2MB) memory disks anymore! When I tried last (June 2004) the
problem existed only for md's larger than about 8MB.

Just to make sure it's not my mistake (would be good news ;-)) here
is what I did:

- hardware: Soekris net4501, Compact Flash
- built kernel using NET4501 config plus the following options:
	options MEMORY_DISK_HOOKS
	options MEMORY_DISK_IS_ROOT
	options MEMORY_DISK_SERVER=0
	options MEMORY_DISK_ROOT_SIZE=4096
	pseudo-device md 1
- created root fs directory structure (/sbin/init, /in/sh, /lib/...,
  /dev/MAKEDEV, etc)
- makefs -s 2m md.img dir
- mdsetimage netbsd.NET4501.MD md.img
- gzip -c netbsd.NET4501.MD >netbsd
- I PXE booted the net4501 using NetBSD 2.99.10, and used fdisk,
  disklabel and newfs to create a filesystem on the CF
- copied /usr/mdec/boot and the gzipped ramdisk kernel to /
- installboot -v -o timeout=3 /dev/rwd0a /usr/mdec/bootxx_ffsv1
- reboot

Booting the net4501 resulted in an endless reboot loop (boot messages
are attached).

Is this supposed to work as described above, or did I miss something?


Help is appreciated.

TIA, Jukka
