So you have only emu10k1 as the sound card? At best, give alsa-info.sh output. I've tested emu10k1 on my machine for long time, so it's strange that such a problem happens.
Unfortunately, I'm traveling in the whole this week, so cannot debug so much locally with the machine.
In anyway, please make sure that the sound driver is really the culprit. For example, add the sound driver modules to blacklist, boot and confirm that the boot works. Then remove the blacklist again and reconfirm that the boot hangs.
Once when you confirm it, try to revert two commits: 7af142f752116e86adbe2073f2922d8265a77709 257f8cce5d40b811d229ed71602882baa0012808
Let me know whether this makes booting again.
thanks,

OK, steps I took:
Obtain alsa-info.sh output from my working 3.17.0 kernel set-up;
Boot into 3.17.0+ and attempt to run alsa-info.sh - dumps occurred as shown in attached photos, even corrupted the machine's BIOS;
Attempt to blacklist sound drivers, ran 3.17.0+ without lock-up, obtained alsa-info.sh output;
Applied 2 reversions listed above to current 3.17.0+ Linus git head, had to remove a few other sound cards from the menuconfig to let the kernel build, removed blacklisting and rebooted into kernel with reversions applied.
Ran alsa-info.sh and received dmesg output as shown below, was able to bring up the desktop session without lock-up.
Regards,
Arthur.
