HP-2140 won't boot with dual-core enabled

[Jeremy Nickurak]

Binary package hint: linux-image-2.6.28-12-generic

When dual-core support is enabled in the netbook's BIOS, an HP-2140 fails to boot. (When the machine boots Windows with dual-core support enabled, hyperthreading is available to present 2 CPUs)

There's many lines of kernel output. I can't grab the first ones (they scroll off the screen), but the ones on the screen (excluding the hex codes except for the last couple) are:

pci=noacpi doesn't help

acpi=off gets the system booting, but then it a) doesn't see the hyperthreading, and b) X locks with a black screen.

[Valde_91 (claudio-brenni)]

Also here!

My 2140 boot with dual core option enabled, without the acpi=off option. The 2140 it's faster with this option enabled. Also stand-by works.

The problem is when I hibernate the pc: when I reboot I've got a similar screen, with these kernel's output lines.

And Acpi is able to detect if the lid is open or close, but even if the power-manger is set to stand-by on closed lid, nothing happend.

thanks Valde_91

[Jeremy Nickurak (nickurak)]

Valde: Are you saying your 2140 boots successfully with dual-core enabled? Mine doesn't boot even once.

The acpi lid-close bug is filed as https://bugs.launchpad.net/bugs/376793

[Valde_91 (claudio-brenni)]

Yes my Hp 2140 with dual core mode.

But: 1. I've tried only booting up from battery. (following this thread: http://ubuntuforums.org/showthread.php?t=1088743& page=3, the bug is present when you start with AC cable)

        2. I've installed ubuntu with the dual core disabled

Last thing, I don't know if that could do any difference, I use ext4 format on my HD

Bye bye

[Jeremy Nickurak (nickurak)]

I've since confirmed that this problem only occurs when the AC power is plugged into the computer. If I plug in the AC adapter AFTER booting, I can keep hyperthreading working. I've only tried this for a little while at a time, so it's unclear if there's other side-effects.

[Valde_91 (claudio-brenni)]

Today i boot my 2140 without the cable. I hibernate the pc. First trying to rebbot fails: I had a screen similar to the one reported. So I forced shut down by pressing the shut down button. Then I rebooted, the 2140 wakes up correctely from hibernation, hyper-treading was still working and even closing the lid put my pc in stand-by.

So I wondering what tyoe of information are reseted in a forces shut down? because after this the ACPI module seems to work perfectly.

thanks Valde

Ah, that's why it doesn't work.
Same problem here. I didn't have this problem with the previous version of ubuntu, only on jaunty...

[joko (giorgiochiodi)]

My system boots on battery, no luck with the power cable attached.
Sometimes it won't boot even on battery power.

http://forums.fedoraforum.org/showthread.php?t=218219 suggests adding a boot_delay=5 kernel parameter to grub.

[Yan Maurakh (yan-maurakh)]

Guys, did anyone try possible solution? Dit it work ? I'am talking about adding boot_delay=5 in grub or kernel 2.6.29

[Jeremy Nickurak (nickurak)]

The boot_delay one didn't work for me, but others reported success.

[Freestyler (freestyler-kiev)]

Have same problem, methods AC Power Off & boot_delay didn't work.

[Jeremy Nickurak (nickurak)]

Appears to have gone away when I upgraded to kernel 2.6.29-02062904-generic from the kernel-ppa

[joko (giorgiochiodi)]

thanks, but boot_delay didn't help at all.

[peter (str3zz)]

confirmed - upgrade to 2.6.29.4 (2.6.29-02062904-generic) from kernel-ppa fix this behaviour

[wtsch (trash4inbox)]

Is the kernel 2.6.29.4 (2.6.29-02062904-generic) from kernel-ppa optimized for netbooks?

[Jon Hale (jon-gorillacon)]

Are there up-to-date instructions anywhere for how to perform the upgrade to 2.6.29.4 (2.6.29-02062904-generic) from kernel-ppa?

I seem to be looking at a bunch of out-of-date wikis for doing this and am missing the correct incantation.

[Jon Hale (jon-gorillacon)]

OK, I figured out how to do that, for other people in the same boat:
wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.29.4/linux-headers-2.6.29-02062904-generic_2.6.29-02062904_i386.deb
wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.29.4/linux-image-2.6.29-02062904-generic_2.6.29-02062904_i386.deb
wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.29.4/linux-headers-2.6.29-02062904_2.6.29-02062904_all.deb

Then:
sudo dpkg linux-*.deb

Then after I rebooted (and changed my bios settings for hyperthreading) linux boots and sees two processors (at least according to the system monitor).

[Jon Hale (jon-gorillacon)]

typo in my last step... s/b

sudo dpkg -i linux-*.deb

[Gyorgyi Toth (tgyorgyi27)]

Hi, I tried this suggestion, and I too had the two CPUs in systems monitor, BUT NO WIFI. Has anybody else experienced anything like this? I have booted now 2.6.28-14 and the wifi works again (but of course I had to disable dual core).

[Bane (rudlavibizon)]

@gyorgyi You need to compile kernel modules for broadcom drivers. I did this with 2.6.29 but unfortunately not with 2.6.30 though some people did it with success. Useful link: http://ubuntuforums.org/showpost.php?p=7389529&postcount=30

[Gyorgyi Toth (tgyorgyi27)]

@Bane Thank you, I have actually read part of that thread, but am not experienced enough yet to read the right things out of it obviously... I've started using Ubuntu 1 year and 2 months ago, and had fun with learning something week-by-week... and I think I learned most because of the bugs along the way, and of course because of folks ready to spend time answering even very obvious questions.

[Kenjie.-San (darthkenjie)]

same to me. i am using kubuntu 9.04.
sometimes it was possible for me to start with dualcore and it was recognized, but after rebooting the system did not come up or it was not available.
