Hi There,
Using DSM 6.1 for 4 days now, and works good. Also SN works good. I use SN from Old broken DS209j.
Only bad thing is Airplay/DLNA. From DS Audio i stream my music to my Onkyo receiver. After a day, DS audio cannot find my Onkyo anymore. After reboot it works for about 1 day. DS Video keeps working, and also find my Onkyo (and TV).
I've a HP Mediasmart X495 server and i only can boot with 3 HDD's, after boot i can add 4th drive. So it is not easy to reboot...
Some people have same problem?
