Some issue in dsm-g600 using netbsd 6.0 release

[Charles Brown <obigiankenobi%gmail.com@localhost>]

Hello,
I'm trying to use netbsd 6.0 in dsm-g600.
I have some issue:
1) I Can't install packages available in:

ftp://ftp.netbsd.org/pub/pkgsrc/packages/NetBSD/sandpoint/6.0_2012Q1/All/

Installation of Samba3.6 was ok, but when I try to start daemons, I have problems with missing libraries (libcrypto 7.0).

2) When I try to build from scratch Samba 3.6.9 the system hangs after a few hours: CTRL+T and DDB are available, but seems that under heavy disk activity netbsd hangs with a missing interrupt (?).

3) When I use static ip addresses, everything is ok, but enabling DHCLIENT in rc.conf, a crash dump happens on FTP file transfert (inbound and outbound):

This happens also using samba.
Using static addressing, both ftp and samba works fine.
Have someone faced or solved these issues?
Kind regards.
