I am on x86_64 with latest (v2.6.34) kernel. When i set
CONFIG_SND_HDA_INTEL=Y It hangs at an early stage in boot with kernel

When i use CONFIG_SND_HDA_INTEL=M the machine will boot, and i get the
dmesg (below).
I have bisected down to one commit that causes the problem:
commit 3e3da00c01d050307e753fb7b3e84aefc16da0d0

I CC'd Yinghai, the author of that patch. That commit went in after
2.6.33, so this is probably a regression between .33 and .34. Can
you open a report at https://bugzilla.kernel.org and respond to this
thread with the URL?
Please attach the complete dmesg (with SND_HDA_INTEL=m) to the
bugzilla.
Thanks a lot for your report!
please send out bootlog with pci=earlydump.
looks like your system have a very sick BIOS,
system have two HT chains.
