Subject: udevd cannot modprobe snd-hda-intel with 3.9.8

Hello,

at boot udev (175-7.2 from debian unstable) blocks for maybe 30 seconds 
and then gives (handcopied)

  timeout: killing '/sbin/modprobe -b 
pci:v00008086d0000293Esv0000144Dsd0000C045bc04sc03i00'

when booting 3.9.8. 3.8.13 has the same issue, 3.6.0 is fine.

The pci id matches the audio device and in fact the module is not loaded:

00:1b.0 0403: 8086:293e (rev 03)

00:1b.0 Audio device: Intel Corporation 82801I (ICH9 Family) HD Audio 
Controller (rev 03)
	Subsystem: Samsung Electronics Co Ltd Device c045
	Flags: bus master, fast devsel, latency 0, IRQ 46
	Memory at f8620000 (64-bit, non-prefetchable) [size=16K]
	Capabilities: [50] Power Management version 2
	Capabilities: [60] MSI: Enable+ Count=1/1 Maskable- 64bit+
	Capabilities: [70] Express Root Complex Integrated Endpoint, MSI 00
	Capabilities: [100] Virtual Channel
	Capabilities: [130] Root Complex Link
	Kernel driver in use: snd_hda_intel

In /etc/modprobe.d/options.conf i have:
options snd-hda-intel model=ultra

A manual `modprobe snd-hda-intel` works perfectly fine:

[16018.432762] snd_hda_intel 0000:00:1b.0: irq 46 for MSI/MSI-X

/devices/pci0000:00/0000:00:1b.0/sound/card0/input15

I've tried both these with 3.9.8 but does not change anything:

The only sound related change from 3.6.0 config to 3.9.8 one is:
