Update from 8.2.0 Release to 8.3.0 Release Hangs

[Yell]

I'm having a huge Problem moving from 8.2.0 Release to 8.3.0.
(Also created ticket: https://support.freenas.org/ticket/1881 )

Problem:
Cannot "warm" reboot Freenas 8.3.0 Release x64 and above with:
- WebGUI
- shutdown -r now
- reboot

Starting works only if i cleanly shutdown the system prior or removing the power cord for 5 min (after trying a reboot).


Things i tried, which result all in the same error and system freeze:

- GUI upgrade from a fully working 8.2.0 x64 Release -> Error
- Fresh install 8.3.0 Release x64 -> load config from WebGUI -> Error
- Fresh install 8.3.0 Release x64 -> Reboot -> Error
- Cold Boot with removed HDD Caddys -> works -> Reboot -> Error
- Cold Boot with removed Sata Cables -> works -> Reboot -> Error
- Tried FreeNAS-8.3.1-ALPHA-r12712-x64.img -> boot ok -> Reboot -> Error
- loaded BIOS default
- disabled/enabled mostly all options (there arent that many, like a notebook BIOS)
- Testing 2 other USB Sticks -> Error

Code:

atapci0: [ITHREAD]
ata2: <ATA channel> at channel 0 on atapci0
ata2:  [ITHREAD]
ata3: <ATA channel> at channel 1 on atapci0
ata3:  [ITHREAD]
uart2: Reserved 0x0 bytes for rid 0x10 type 4 at 0xf148

(Last line is from booting with verbose logging)

Info:
Prepared the USB stick from my Fedora Desktop with the following command:

Code:

xzcat Downloads/FreeNAS-8.3.0-RELEASE-x64.img.xz | sudo dd of=/dev/sdc bs=64k

Hardware:

Code:

Intel DH55TC (Mainboard 6x sata onboard, and latest BIOS)
Intel Core i3 530 2.93GHz
4x WD20EARS  2x WD20EARX
2x 3in3 Xigmatec HDD Cages

Does this mean 8.3 Release doesn't support rebooting "?

Rebooting FreeBSD 9.0 from USB (memstick) and installation ( on2.5" hdd in hotswap bay) both work.
