Boot with 'acpi=no'-Ubuntu shows one core,normal boot-kacpid process is eating 70%CPU
Hi,
I am facing very strange problem.Ectually its started coming up from first day.At the time of installation i had to use 'acpi=no' boot parameter because without it system just got hang.Now if i boot without 'acpi=no' 'kacpid' process is eating 60%-70% CPU and if i use 'acpi=no' boot parameter Ubuntu is showing only one core of my Dual core processer.
I know acpi is creating some problem.Here is the out put of 'dmesg | grep CPU' command
As you can see it is showing and using only one core of Dual core processor...
How to solve this problem?I searched a lot about this but unable to find any solution.
My system specs are..
Intel Pentium D processor 3.0 Ghz
Intel 945GCNL motherboard
Windows XP + Ubuntu 7.10(Dual boot)
If I use the Kubuntu, 64 bit desktop cd I get both processors but recently on my system running Kubuntu 32 bit, I only get 1 processor. I posted more details on the ubuntu forums. http://ubuntuforums.org/showthread.php?t=697423. I found your post while looking for possible fix for mine.

I searched a lot and found that Ubuntu has this kinda problem with no solution...this need to be sort out.Because we all love Ubuntu...
I think it has something to do with the kernel, but my wife's laptop is working fine. It took a while, several days over all but I got it working again. I ended up recompiling the kernel, and here is what I posted in the thread: http: //ubuntuforums.org/showthread.php?t=697423

It wasn't quick and easy, but I recompiled the kernel to 2.6.24.2 using KernelCheck http://kcheck.sourceforge.net/ which worked but I needed to do it several times until I learned you had to go into go into the configuration for Sound Advanced Linus System under PCI devices and select the HD Sound for the iIntel - even though I am not using the intel, in order to get the sound working.
In the process II also selected the "K7" option as I am using an AMD 64 dual core. I also needed to select memory higher than 4 gig so my full 4 gig of memory would be recognized. The first time I thought selecting 4 gig would do it, but had to go with the 64 gig - took several tries to get it all working.
The last compile I used the directions at http://ubuntuforums.org/showthread.p...=master+kernel
because I didn't need to download the source again and I didn't know how to set up kernelcheck to set up and compile without doiwnloading everything. It took a long time, several hours to recompile the kernel several times, I almost gave up and was ready to install the 64 bit version.
I needed to run envy again to reinstall my video drivers and I had to reinstall VirtualBox but it now seems to be working. I hope this helps someone else.
Solution to kacpid which works fine for me :
After booting windows when boot linux kacpid starts, to stop it just cut the power supply to your PC including UPS if any , without shutting down (obviously after saving data) when linux desktop is active. yes i am saying that take the power cord out.
Now switch on the power of ur machine & boot linux, kacpid will not appear.(hopefully)
