This one makes my Soundblaster Live (alsa/emu10k1) silent.
It is detected, i can e.g. change the mixer, but i can't hear any sound.

Updating from 3.2.4 the emu10k1 driver was among the few that was 
recompiled after the update to 3.2.5. (Technically i look for that when 
i downgraded to 3.2.4, but i think there number of recompiled files 
should be the same in either direction)

After downgrade to 3.2.4 i have sound again.

There is a difference in syslog output regarding aspm, the emu10k1 line 
is the same.

3.2.4:
ACPI FADT declares the system doesn't support PCIe ASPM, so disable it
...
ACPI _OSC control for PCIe not granted, disabling ASPM
...
e1000e 0000:03:00.0: Disabling ASPM  L1
...
snd_emu10k1 0000:06:02.0: PCI INT A -> GSI 16 (level, low) -> IRQ 16


3.2.5:

Real Programmers consider "what you see is what you get" to be just as 
bad a concept in Text Editors as it is in women. No, the Real Programmer
wants a "you asked for it, you got it" text editor -- complicated, 
cryptic, powerful, unforgiving, dangerous.
