Description José Luis Patiño Andrés 2010-01-05 05:04:09 UTC 
User-Agent:       Mozilla/5.0 (X11; U; Linux i686; es-ES; rv:1.9.1.6) Gecko/20091201 SUSE/3.5.6-1.1.1 Firefox/3.5.6

Simply, when I boot my laptop I take this message at kernel log repeatedly (around 10 consecutive times):

[    0.036267] BUG: scheduling while atomic: swapper/0/0x10000002

After this, the boot continues normally and system runs without any problem (apparently).

My laptop is a Lenovo 3000 N100, using Intel chipsets and a Centrino Duo T2300 processor. Here yo have a 'lspci' response from it, for your consideration:

I attach the /var/log/boot.msg file to give you more data from the log. In order to made reading more easy, I tell you that the problem appears in the log from [0.018393] to [0.382040] (kernel running time).

Thank you very much.

Reproducible: Always

Steps to Reproduce:
1.Just boot the computer.
2.GRUB takes the OS choice openSUSE.
3.Kernel boots and the error appears.
