Centos 4.4 guest makes host CPU goes 100 even the guest is idle

Running a Centos 4.4 guest under VirtualBox 1.3.6 makes the host CPU goes 100% even after boot.
I also have Windows XP and Ubuntu 7.04 guests and they both worked well with host CPU dropping just after the boot.
When running Centos 4.4 guests, "top" on host shows 100% busy and "top" on guest shows 99% idle.
My host is a Ubuntu 6.10, default Ubuntu kernel, and it has a dual-core CPU.
I already tried other Centos kernels, disable ACPI, and reinstalling Guest Addictions but with the same results.
The last test was install the Fedora3 kernel (2.6.9-1.667) that is only a bit older but at least install without dependency problems and IT DID GREAT! Host and Guest CPU were minimal after boot just like the other OS's I tested.
So it look like a Centos kernel specific problem when running under VirtualBox.
The kernels I tested:
- Centos 4.4 kernel-2.6.9-42.0.8.EL (100% host cpu usage after boot)
- Centos 4.4 kernel-2.6.9-42.0.8.plus.c4 (100% host cpu usage after boot)
- Fedora FC3 kernel-2.6.9-1.667 (0% host cpu usage after boot - good)
