I try to get FreeNAS 0.686.1 stable running since a couple of days. Installations with usb cdrom works fine, but when rebuilding graid5 array "RaidDATA", after a couple of minutes (no exact time - varies an can be just a few seconds after reboot), the system hangs, last message on console saying "ata2: DISCONNECT requested". I searched FreeBSD newsgroups, and you can find some issues, but no solution.
ASROCK Board with Sempron Proc., everything disabled except for IDE0 (Transcend Flash 512MB) and COM1
using PCI card SATA controller <SiI 3112="" SATA150="" controller=""> and onboard controller <VIA 6420="" SATA150="" controller=""> attached: 4x Maxtor 300GB
Do you need further information?
Thx for your help
PS: ACPI on or off does not change the matter
