Description stadtkind2 2011-12-10 12:20:05 UTC
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.
Comment 4 nukama 2014-06-09 12:59:13 UTC
I've to put hint.hdac.0.disabled="1" into /boot/device.hints to run
FreeBSD-11-CURRENT-r266655 on a Via EPIA-M910-12PQ QuadCore.

Otherwise it hangs during boot.

I can confirm that this bug also afflicts 11.0-RELEASE, and nukama's workaround still works.
