Romain, I'd sas that for additional troubleshooting the issue the following
article may give you some hints:
http://linoxide.com/how-tos/cpu-bottleneck-linux/
You should have the following packages installed: procps and sysstat.
First, maximize the terminal window. Then run vmstat and mpstat
I've set Htop as you said.
Here is the new screenshot. Nothing is different.
That's strange it's like the system thinks my computer just has a one core CPU.

Romain, red CPU time is related to kernel. In htop you can press F2 and
set display options as shown on the attached screenshot in order to get
more details on kernel threads. (Press Esc to go back to process list.)

Maximize the terminal window, start htop and sort processes by CPU% (F6,

I'd like to confirm that this bug exists in Ubuntu 11.04 with
Linux 2.6.38-9.43 on a Toshiba nb300.
As a workaround I set
GRUB_CMDLINE_LINUX_DEFAULT=quiet splash nolapic_timer clocksource=jiffies
in /etc/default/grub and then run
sudo update-grub
sudo reboot
Note that the right option name is
More likely to be a kernel problem than X. I see this already has a

In my case 'nolapci_timer' alone did not fix the issue.
It boots as quickly as 'intle_idle.max_cstate=0' but has more frequent pauses
once it has started.

problem, however I will test it out some more and report back if

I can contradict previous reports.
The intel_idle.max_cstate=0 option decreases freezes, but they still exist, as

try adding clocksource=jiffies nolapic_timers to the kernel command line
parameter.
sudo pico /etc/default/grub
change
GRUB_CMDLINE_LINUX_DEFAULT=quiet splash
to
