[SOLVED] Debian (AMD64 - squeeze) - booting takes a long times

vharishankar · 06-11-2009, 11:36 AM

Here's a peculiar problem I've had ever since I got the 2.6.26 kernel in place.

Whenever I boot the system, the booting process kind of hangs up for around 90 to 100 seconds at around this point, when the ACPI messages are displayed

Code:

...
...
[   10.542278] iwl3945: Copyright(c) 2003-2008 Intel Corporation                
[   10.542278] ACPI: PCI Interrupt 0000:02:00.0[A] -> GSI 16 (level, low) -> IRQ 16                                                                             
[   10.542278] PCI: Setting latency timer of device 0000:02:00.0 to 64

[   10.588079] iwl3945: Tunable channels: 11 802.11bg, 13 802.11a channels      
[   10.588119] phy0: Selected rate control algorithm 'iwl-3945-rs'              
[   10.685080] ACPI: PCI interrupt for device 0000:02:00.0 disabled             
[   10.707510] udev: renamed network interface wmaster0 to eth2                 
[   10.815934] ACPI: PCI Interrupt 0000:00:1b.0[A] -> GSI 22 (level, low) -> IRQ 22
...
...

After 100 seconds the boot process continues normally. And this happens every single time I boot. Whatever else happens, it always seems to stop at that particular line, which has been bolded here.

This problem hasn't occurred before... very strange - I'm unable to figure out the underlying problem.

My system is a HP dv6314 laptop running Intel Core 2 Duo 1.73 GHz, 2GB RAM and Debian resides in an 80 GB reiserfs partition alongside Vista.

Could anybody give me some suggestions as to what might be causing this?

Unneccessary module in kernel?? A bug??

vharishankar · 06-13-2009, 06:59 AM

I'm not sure it is a bug in the kernel, by the way, because others MIGHT have reported this problem before. But searching these forums, I've not found a single post on this particular subject.

This happens only when I boot from "scratch" and not when I restore a "suspend-to-disk" session. Could this possibly be related to the suspend script?

From what I can see it's related to ACPI though.

lugoteehalt · 06-13-2009, 07:17 AM

On my machine Lenny testing was as buggy as hell - as buggy as a Yak's jockstrap. So I just thought it might be that.

You could perhaps try getting rid of ACPI and replacing it with APM (is that what it's called?) Advanced power management.

Could you try the 2.6.29 kernel?.
See if you still get a hang with a different kernel.
The reason i say this is because the 2.6.26 kernel hangs at boot on my machine,although with a different error message.
On Googling the error it pointed to a bug.
See my thread here:

http://www.linuxquestions.org/questi...-lenny-673596/

These problems only appeared with the 2.6.26 kernel.
Previous versions booted without problems(2.6.18,2.6.24)
I am currently using 2.6.29 from Sid without problems.

vharishankar · 06-13-2009, 08:43 AM

Thanks for confirming that 2.6.26 has problems! I knew that I would not be the only one facing this problem, yet I couldn't define it in any way which would be easy to describe.

I will probably have to get 2.6.29 from unstable and see if that helps in any way.

Isn't APM deprecated? I remember that it never used to work properly when I tried it, but it's such a long time ago, I don't actually remember.

vharishankar · 06-13-2009, 11:39 AM

I tried installing 2.6.29, but it still doesn't work.

The common factor is that message about
GSI 22 (level, low) -> IRQ 22

Could this be related the onboard sound HDA Intel?

It seems to hang up on that message for around 90 to 100 seconds every time.

It is most annoying

Dutch Master · 06-13-2009, 11:47 AM

You may want to assign IRQ 22 manually in the BIOS of your mainboard. It appears to be in conflict with another device in your system. Alternatively, your hardware might be failing: how old is it?

vharishankar · 06-13-2009, 11:53 AM

I just saw the bill. I bought the laptop on December 2007. Not yet two years old.

By the way I have Vista Ultimate OEM on the same system (dual boot) but I haven't noticed any slowdown in boot up time for Vista.

By the way, it does appear to be an IRQ conflict. Thanks for pointing in the right direction, Dutch Master.

vharishankar · 06-21-2009, 09:45 PM

Just as an update: this problem occurs with Kernel 2.6.30 also.

Always hangs for around 90-100 seconds at the message IRQ 22.

I am unable to modify any settings related to IRQ in the BIOS as there are none. This is a notebook and the BIOS has very limited options.

the trooper · 06-22-2009, 05:29 AM

Could you try booting with the noacpi kernel parameter?

vharishankar · 06-22-2009, 05:54 AM

I'm a heavy user of "suspend to RAM" and "suspend to disk" but I'll give this a try and see if it helps.

vharishankar · 06-22-2009, 07:46 AM

No such luck. With ACPI off, booting still pauses for 90-100 seconds at the same spot and worse, X becomes slow and unresponsive.

I'm sure it's not a hardware problem though. Windows Vista on the same laptop boots as quickly (or as slowly) as it used to before this problem.

I first noticed this after I had upgraded from 2.6.24 to 2.6.26 kernel and it has been present since.

vharishankar · 06-22-2009, 09:41 AM

I tried with APIC turned off, but that prevents the system from booting - stops at "media not found" message.

the trooper · 06-22-2009, 12:49 PM

Well i'm all out of ideas.
The only other suggestion would be to submit a bug report to Debian,explaining that these problems have come about since upgrading the kernel.
The following guide may help for composing bug reports:

You can use reportbug or contact Debian via e-mail.
