I buyed a Notebook from SAMSUNG, the Samsung SA11 Aura P7350 Degas.
The Processor is an P7350 Core 2 Duo with 2x2Ghz:

First, I couldn't use any Linux 64bit (amd64) distribution. Then, i tried under gentoo the "acpi=off" bootoption. This works.
Why is it, that ic cannot use the ACPI features under 64 but 32bit? I allready tried to suspend with a 32bit kubuntu, and it worked well. What can I do to fix this? It's necessary on a notebook to have ACPI, isn't it?

Hi,

Not necessary but interesting for sure.

What does it do/tell when it fails ? (error message and stuff)

Regards,
Maxime

No messages, only reboot. This is part of the problem. But powersaving is necessary for notebooks!!

Hi,

Useful, enjoyable, great, a very big plus ... but not nececessary ;)
Have you tried with a 64-bits version of another distro ? Kubuntu 64b ?

[EDIT] Oops ... My mistake, forget && forgive the last question ^^;
Honestly I don't know if it works or not for a 64bits, but doesn't see why it wouldn't. Plus, if you can disable it, it means that it's enabled, therefore it's there for a reason. It must be possible.


Regards,
Maxime

This is not normal. ACPI has worked under 64 bit gentoo for at least 4 years.

I'm installing 64-gentoo from the cd with "acpi=off" in the meantime. I hope i can enable ACPI later on my harddisk kernel.
I hope i got some errormessages then.

I don't want to expand this discussion, but a mobile computer should use all the energy-saving features it got to encrease its running time?! And that's what the ACPI does.

Hi,

Yes, I totally agree with you !
My point is just that necessary means "a needed, sine qua non, condition to functionnate", as in the mathematical term "necessary".
But perhaps I'm just being a non-English speaking scientific/mathematic freak here :D

Anyway, keep us posted on this topic once you'll have some more info/error messages, I'll try to help as best as I can.

Regards,
Maxime

Check your BIOS to make sure you're ACPI setup is proper. If there are no settings for your ACPI under the BIOS, then it is set properly, and you have a kernel issue of some sort. In that case, post your .config, the results of lspci -n and cat /proc/cpuinfo as well as your /etc/fstab file, and I'll see what I can see there.

Blessed be!
Pappy

I allready checked this, no settings for ahci.
I can only disable SpeedStep and a PowerDown-Mode of the processor.

It occured while booting from the amd64 install cd, 2 steps after unpacking firmware. Because I tried to start without ACPI, I know exactly where it is. The system reboots at the step, where the ACPI features are loaded.

At this moment, i got a 64bit system installed. But now, the system freezes while I'm compiling the kernel (but at a fewer time this wasn't a problem). Im currently trying to compile it with the installcd.
When this problem happens, I can switch to evry console (Alt-Fx). I can type some text in their command lines. I can press the enter key, but nothing more happens. No halt command, o reboot command... -.-
Edit: COmpiling it via cd worked, i'l gonna try it now...

pappy is planning to write up a kernel .config for you. To ensure the resulting kernel can mount your filesystems, he needs to include support for all the filesystems you used. Asking for fstab, which has the filesystem as one field in the mount line, is easier than asking you to manually enumerate all the filesystems you need supported. It is also a quick way to check whether someone is using the old IDE drivers or the newer libata drivers, which assign different names to your hard disks. If you used one and he picked the other, /etc/fstab would be using the wrong names, from the perspective of the new kernel.

That's cool!^^
But I add some Bluetooth myself later? And I got to compile this kernel via livecd, cause at the moment I cannot do anything that takes more then 5 minutes on this system, beacause it freezes...

sounds great.
Maybe i can ask Pappy also to bake me a kernel :D
Wonder what would be different with my curent config :)

If I connect or disconnect the AC adapter under a running linux 64bit, the system reboots quietly. This showes again, that ACPI does not work correctly.
Should I give up this and simply install gentoo 32bit?

Your .config was a complete mess. I started fresh with one of my seeds. There was so much instability in that kernel, just about anything could make it ill.

Hu is correct. I can't whip up a kernel .config without knowing which file systems you are using. And while I could turn them all on, that would defeat the minimalist nature of my kernel seeds.

Also, yes, you can add bluetooth to the kernel...after we have given you a more stable system. For the moment, let's make sure the ACPI issues are fixed, and move from there.

Click here for your new .config. Compile as is.

For the best results, please do the following:
1) Move your .config file out of your kernel source directory (/usr/src/linux- ).
2) Issue the command make mrproper. This is a destructive step. It returns the source to pristine condition. Unmoved .config files will be deleted!
3) Copy my .config into your source directory.
4) Issue the command make && make modules_install.
5) Install the kernel as you normally would, and reboot.
6) Once it boots, please post /var/log/dmesg so I can see how things loaded.

Since I read that you also had lockup issues, this is as much a troubleshooting tool as anything. If your system stabilizes, then we know it was a bunch of kernel issues. If not, you might have hardware issues.

Blessed be!
Pappy

Weird, perhaps, but I take my geeking seriously. I didn't start my life reading The How and Why Wonder Book of Things, only to decide to start reading My Pet Goat as an adult. hehehehe. By the way, love your sig! I made my choice a LOOOOONG time ago.

Ok, now that's out of the way, your kernel was a bit on the messy side as well. I started with a fresh seed. I'm just bummed that I can't watch it boot with the new kernel. Quad core...nice. You can build on the base of the seed, but please don't waste that CPU power on CPU scheduling or the like. Open the throttle and let 'er rip!

Click here for your new .config. Compile as is.

For the best results, please do the following:
1) Move your .config file out of your kernel source directory (/usr/src/linux-2.6.30-gentoo-r1 ).
2) Issue the command make mrproper. This is a destructive step. It returns the source to pristine condition. Unmoved .config files will be deleted!
3) Copy my .config into your source directory.
4) Issue the command make && make modules_install.
5) Install the kernel as you normally would, and reboot.
6) Once it boots, please post /var/log/dmesg so I can see how things loaded.

Enjoy!

Blessed be!
Pappy

Really thanks for your kernel configuration.
But I got bad news. The ac/battery switch problem still exists. The system reboots quietly.
Should I add some ext4 support?

dmesg.log after using new kernel: dmesg_new.log

But leastwise it runs and don't freezes any more...

Edit:
I got an error: ..."nvidia.ko" needs unknown symbol (un)register _cpu_notifier
And I got no ethernet. NVIDIA graphic doesn't run.

Should I give up and use 32bit? Maybe I can switch to 64 later... -.-

RealBluescreen: you need to set MTRR values in the kernel, i have same thing.
Code:

CONFIG_MTRR=y
CONFIG_MTRR_SANITIZER=y
CONFIG_MTRR_SANITIZER_ENABLE_DEFAULT=1
CONFIG_MTRR_SANITIZER_SPARE_REG_NR_DEFAULT=1


pappy_mcfae: work kinda, only feels a bit slower than before :)
Here's the dmesg

Oh, and iptables say something they must not say:
Code:

iptables: No chain/target/match by that name.

Enter emerge -av acpi acpid && rc-update add acpid default. Then reboot and retest.

Blessed be!

I didn't see anything strange in the dmesg. All four cores fired up, all the net devices came up, and so on.

As for the iptables trouble, the .config I sent has iptables turned on; ipv4 and ipv6. Try changing those settings to modules and recompiling the kernel. There may be some further tweaks needed. We'll discuss those as they arise.

Blessed be!

Reinstall nvidia-drivers. The compile a kernel module, and when the kernel is changed it may needs recompilation

NVIDIA drivers doesn't work, and I got that compile problem again.
System freezes while compiling sth. The processor isn't under load then.

Edit:
It looks like that compile problem only happends with activated MTRR; At the moment I deactivated this, and it works. But as Autie said, I need this for my nvidia-drivers?!
What should I do?

  • ACPI doesn't run regular under 64bit (Switching AC/battery doesn't work). Under 32bit, evrythings fine.
  • If I add MTRR to the kernel under 64bit, I cannot compile something,
    but I need MTRR to use NVIDIA (by the way, what doesn't works anyway... -.-)
  • but this notebook is not bad. A good processor for a good price.


I got a week left to revoke this purchase. Is it possible, that this ACPI problem will be fixed in a few months, and use 32bit in the meantime? Or should I by another notebook?
