Hi all,

I have a Clevo laptop (sold as Xxodd) with an Intel P9500 and 4GB Ram.

Some history:
I purchased the laptop (last summer) and tried to install the current Ubuntu 64-bit and Fedora 64-bit.
The effect in both cases was endless rebooting and I couldn't get it to work.
I installed CentOS 5.2 64Bit and was able to get most of the system working. One of the remaining anoyning problems was that when I do 'shutdown' the system woould shutdown and reboot.

Now last week I upgraded the system to CentOS 5.3 64Bit (newer kernel) and I was faced with this problem again.
Because centOS has an Interactive startup I figured out that the system rebooted during the startup of the "kudzu" and "cpuspeed" services. So I disabled these and the system worked (always at fullspeed :( )

yesterday I read this bug report and descided to try the mentioned mem=4096m solution.
So I added the mem=4096m option (to my CentOS 5.3) and all my troubles have gone. The system now works like a charm and also when I do a shutdown the system actually powers off when I shutdown.

My assesments based on this and all the stories above: This is a kernel issue.
