[kernel_thread_helper+0x0/0x10] boot Live CD fail

Could you explain more in detail ? And please provide exact error messages.

[ 0.851246 ] [<ffffffff8100aee0>] ? kernel_thread_helper+0x0/0x10

[ 0.851246 ] [<ffffffff8100aee0>] ? kernel_thread_helper+0x0/0x10

I looked with Google, and there are many solutions (and probably many potential problem).

When Ubuntu CD boot, hit <F6> key, you will see a menu. Select "acpi=off", then key <ESC>.
If it works, we will have to make this permanent by editing file /etc/default/grub:
   GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi=off noapic"

I've tried and "acpi = off" and "noapic" and "nolapic" - both separately and together. If you choose at least one of these options - a black screen.

I write in Russian, translate using "google translate"

Same Problem here, can't install any Ubuntu Version newer than 9.10.

kernel_thread_helper+0x6/0x10

Notebook: Toshiba L650d

ACPI on or off, doesn't matter

Any news?

With such an attitude ubuntu developers will lose all laptop owners "toshiba". Irritating to their silence.

@rolan: Ubuntu developers are benevolent, and you are not alone to have issues today with Maverick. If you want to help on forum, you are welcomed.

As for L650D, update your bios at toshiba website i read that it has solved the problem for many ! Me i'm still waiting for my L655D to have that possibility !

Thank you, but the BIOS at the Toshiba Homepage is from 08/06/10 - Version 1.40. Thats the Bios I have installed on my L650d. Where did you read about the solved problem?

Excuse me it was for the L650 not L650D
They do nothing for the "Dssssss" so far !

Its a pity, I tried yesterday different things (alternate DVD, different boot options) but nothing worked.

No answer from Toshiba as well ;-(

= No Ubuntu on my Notebook

I have exactly the same situation as that of the fellow with the nickname Ziggert

Try ubuntu 9.10 that one works on mine ! But not 10.04 and 10.10.
Toshiba is not helping much !

And yet, what do the owners of laptops toshiba l650d at the moment? I understand, the problem is solved or not, or it will be resolved in version 11.04. Personally for me it's the collapse of Ubuntu.

Yes, the problem ist still alive.

But I'm not sure wether the Ubuntu Kernels or Toshiba Bios is responsible for the problem.

1) Ubuntu 9.04 and 9.10 work

2) After a Bios update from Toshiba, the installation of Ubuntu 10.04 and 10.10 was no problem on other Toshiba models

So, I'm not quite sure.

At the moment I'm working with Win7. Hope there will be shortly a fix, doesn't matter from wich side.

I also wrote a message in support Toshiba, but they have not responded. bios is the latest. 9.10 actually works, but wifi - could not be established. If you know - how to install the driver wifi - will fit and 9.10.

Yes , well when i said ubuntu 9.10 works on L655D i forgot to say you have to install a driver for the wifi and the ethenet also !
you should have wifi like mine : Network controller: Realtek Semiconductor Co., Ltd. Device 8172 (rev 10)
You can install the windows driver with ndiswrapper (or compile the source of linux driver, if i remember well you have to use the version 8192)
Search on internet the procedure to compile this linux driver. I don't remember how i did it !

Вы не пробовали установить debian на l650d? Думаю попробовать

oops )) Have you tried to install debian on l650d? I think to try

For what i have read Debian has the same problem !

I must admit that my 9.10 installation now is running perfectly !

Probably have to put up with 9.10

As I have anew time, I'm unstacking old questions.
What's the status of your question ?

Now work is time consuming, so I stopped trying to install ubuntu. Nevertheless, if there is a solution or will the thoughts on this, please report it.

The new release of Ubuntu 11.04 Natty alpha seems to have solved this problem !!!
Yeah ! Let's see how it goes with the next releases !
It looks good !

I tried to install the new alpha (alternate version), but black screen after chosing "install".

But there is a Bios update, did anybody tried?

Updated Bios to 1.60, boot still hangs ;-(

@ Ziggert
Did you try just the 11.04 just in live-cd ?
I will try a install soon just to see.

@Jean Lussier What is exact model of your laptop ?
@Ziggert There is now a more recent BIOS : http://www.csd.toshiba.com/cgi-bin/tais/support/jsp/modelContent.jsp?ct=DL&os=&category=&moid=2681244&rpn=PSK2LU&modelFilter=L650D-ST2N01&selCategory=2756709&selFamily=1073768663

Thx, but this bios is not siutable for mine: got L650D 10H PSK1SE

http://de.computers.toshiba-europe.com/innovation/download_drivers_bios.jsp?service=DE

Newest Bios is 1.60

@delance my model is : L655D PSK1NC-01100S

I am also having this issue. Ubuntu 11 was running fine, all of a sudden, I can't load it and live CD crashes.

I forgot to mention, my computer with the same exact proble,, is a self build. Also, windows vista 64 dual boot DOES 'WORK'!

If LiveCD crashes suddenly, you have a hardware issue, as installed Ubuntu is not implied in LiveCD. Could you confirm that LiveCD crashes suddenly (and not only boot from hard disk) ?

I would say the same thing, live-cd problem = hardware issue.
This could be a hard-disk issue or a memory problem. Try a memory check on live CD if you can

Personally , i installed Linux Mint 11 (based on Ubuntu 11.04) on my Toshiba Laptop and it is just great !
I hate Unity and Gnome 3 . That version is giving me the best of Ubuntu and more...
Good luck to you !

yes, it crashes after I choose a distro, or try install. I've also tried to install FreeBSD today. Unix gave me a much detailed view. It looks like pci slots are where my troubles begin, then all sorts of interrupts happen.

I still don't understand why vista is still able to load. Normally its the other way around.
