okay. I just restored to my original Hdmi.conf. "options snd-intel- dspcfg dsp_driver=1" in alsa-base.conf still commented out.
Now the -25 kernel v3 does not boot anymore. I am confused now. I could boot in #15. It is supposed to be the same setting. I got stuck at a black screen. But if I select -26 in the Grub menu (keeping other config files the same), then it could boot easily. I suspect that somehow a filesystem check is triggered at boot time, and maybe that filesystem checking process hangs. Just my pure guess.
