linux-image-2.6.24-15-generic fails to boot - screenshots attached

[Chris Moore]

Both versions 2.6.24-15.26 and 2.6.24-15.27 of the kernel fail to boot for me.

I took a series of photos of the boot messages (with the "splash" and "quiet" options removed) and am attaching them here.

lspci tells me the sound card is:

00:1b.0 Audio device: Intel Corporation 82801G (ICH7 Family) High Definition Audio Controller (rev 02)

I should probably also mention:

* Ever since installing feisty on this laptop, only 2 of the 3 speakers have worked. The central "woofer" is always silent. It works if I boot into Windows XP.

* The volume control has sliders for "Master", "PCM", and "Front". They all control the left and right speakers. The central speaker stays silent. I would guess that "Front" is supposed to control the center speaker. It's actually on the bottom of the laptop though.

* I upgraded to hardy some time ago. these kernels have worked:

I think I am running into this same bug in both 2.6.24-14-generic and 2.6.24-15-generic. 2.6.24-12-generic will still run fine for me, but both 14 and 15 will not boot.

If you reboot, and hit 'e' while you're in the grub menu, then go to
the long line with 'splash' and 'quiet' at the end and hit 'e' again,
you can delete the 'splash' and 'quiet' bits and hit 'b' to boot -
then you'll get to see full details of what's loading and what's
crashing, like in my photos.

Yup, I have the exact same problem. Except it doesn't fail to boot. Though it does take a bloody long time. When it does boot I have no sound though lspci sees the same sound card but "cat /proc/asound/cards" yields:
--- no soundcards ---

I previously noted this at https://bugs.launchpad.net/bugs/213633 but if I down grade the kernel back to 2.6.24-14 it all works fine again.

Oh, well, maybe it doesn't fail to boot for me either, but I wasn't
prepared to wait a bloody long time. I gave it 5 minutes or so and
gave up.

[Chris Moore (dooglus)]

2.6.24-16 also failed in the same way.

I left it this time, and it did finish booting after a 3 minute pause. After booting, sound doesn't work.

I'm attaching the kern.log from the boot.

These lines are included:

Here's output from the command Darryl Moore ran:

$ uname -r
2.6.24-16-generic
$ lspci | grep -i audio
00:1b.0 Audio device: Intel Corporation 82801G (ICH7 Family) High Definition Audio Controller (rev 02)
$ cat /proc/asound/cards
--- no soundcards ---

I'll try the same in the last working version, and also attach a kern.log from booting that.

[Chris Moore (dooglus)]

Here's output from the same commands in the working kernel:

$ uname -r
2.6.24-14-generic
$ lspci | grep -i audio
00:1b.0 Audio device: Intel Corporation 82801G (ICH7 Family) High Definition Audio Controller (rev 02)
$ cat /proc/asound/cards
 0 [Intel ]: HDA-Intel - HDA Intel
                      HDA Intel at 0xfebfc000 irq 22

I'm attaching the kern.log from this working kernel too.

[Chris Moore (dooglus)]

I found a workaround for this:

Make a new file in /etc/modprobe.d/ with a single line:

blacklist saa7134

That restores the boot time to normal, and allows the sound card to work again.

saa7134 seems to be for the TV decoder card, which I've never had working at all.

In kernels where I was having the problem, there are 2 copies of saa7134.ko, and only 1 copy in the kernels which don't have the problem:

/lib/modules/2.6.24-14-generic/kernel/drivers/media/video/saa7134/saa7134.ko

/lib/modules/2.6.24-15-generic/kernel/drivers/media/video/saa7134/saa7134.ko
/lib/modules/2.6.24-15-generic/ubuntu/media/saa7134/saa7134.ko

/lib/modules/2.6.24-16-generic/kernel/drivers/media/video/saa7134/saa7134.ko
/lib/modules/2.6.24-16-generic/ubuntu/media/saa7134/saa7134.ko

[Darryl Moore (darryl-moores)]

Chris, excellent fix! blacklist saa7134 fixes everything for me. It even includes the firefox issue with it always starting in offline mode. I'm sure I don't get the connection, but there it is.

I'm running an acer aspire 9810. It sounds like you are running a closely related machine. I too have never been able to get the tuner to work.

I'm using an ASUS W1J.

Hi Guys,

Sorry for the issues you're seeing here. This has actually already been reported in bug 212271 and is actively being addressed by our kernel developers. I'm going to go ahead and mark this as a duplicate of bug 212271. Please continue to watch that report for any updates as well as for making any future correspondence. Sorry again for the troubles. Thanks.
