[Bug 1092102] Re: udevd timeout: killing /sbin/modprobe -bv pci:

[Bryn Hughes]

I have the same thing on my Asus P5WDG WS PRO board.  Like you it has
Intel sound, and the Intel sound device is one of the "stuck" modprobe
processes.

In my case I get 2-3 modprobe processes stuck with a 'D' state (waiting
on I/O).  This causes my system load average to sit at 2.0 or higher.

root       879  0.0  0.0   4412   708 ?        D    12:47   0:00 /sbin/modprobe -bv pci:v00008086d000027D8sv00001043sd000081F6bc04sc03i00

root       889  0.0  0.0   4376   720 ?        D    12:47   0:00 /sbin/modprobe -bv pci:v00008086d000027B8sv00001043sd00008179bc06sc01i00

I can leave them for a very long time and they do not appear to go away.

>From the dmesg output I suspect we have the same or similar chipsets in
our mainboards.  I do not have this issue with the Precise kernel
(3.2.0-x), but it is definitely there with 3.5.0-19 and 3.5.0-21

  I think the numbers refers to these two devices:

  00:1b.0 Audio device [0403]: Intel Corporation NM10/ICH7 Family High Definition Audio Controller [8086:27d8] (rev 01)
          Subsystem: Dell Device [1028:01de]
          Kernel modules: snd-hda-intel

  00:1f.0 ISA bridge [0601]: Intel Corporation 82801GB/GR (ICH7 Family) LPC Interface Bridge [8086:27b8] (rev 01)
          Kernel modules: leds-ss4200, lpc_ich, intel-rng

  Impact: no sound card.
  This started after i upgraded to 12.04. Got a new kernel this morning, upgraded and rebootet but still the same.
