FreeBSD 9.0-RC3 (well, any RC) hangs when I try to boot the CD on a Via EPIA M850 board.

Verbose boot ouput available at

http://pastebin.com/hf8pU5W9

Last line shown during boot is:

hdac0: Probing codec #1...

and then it completely freezes.
>How-To-Repeat:
Burn the amd64 iso and boot on a 64bit VIA Nano CPU.

 Having a similar hang with an EPIA P820 board. Recompiling the kernel
 (used the -RC3 sources that were on CD) without the snd_hda driver
 allows the system to boot. It seems to come up without a problem.

 A kernel compiled with
 
 nodevice snd_hda
 
 boots indeed fine.
 
 I also tried the hdac patch from
 
 http://svnweb.freebsd.org/base?view=revision&revision=228726
 
 to get support for the VIA VT1708S High Definition Audio Codec on my board,
 still no joy (i.e. booting a kernel compiled with 228726 freezes as well)
 
 Seems like FreeBSD 9.0-REL will be unusable for VIA mainboard owners.

 Same Error on i386 and amd64 on 9.0-RELEASE & 9.1-BETA1 with same error 
 on a VIA EPIA-VE-900 Nano X2 1,4 GHz Dual Core MiniITX Board.
