Bug Description
New 8.04 installs: tried both 32bit x86 and 64bit AMD/Intel
TWO COMPLETELY DIFFERENT COMPUTERS!
Asus M2N-VM DVI
AMD 6000+ Socket AM2 Athlon 64 X2 CPU
4 Gig 800MHz low latency memory
nVidia PCIe GeForce 8600 video card
and
Asus M2NPV-VM
AMD 5600+ Socket AM2 Athlon 64 X2 CPU
4 gig 800 MHz memory
nVidia onboard GeForce 7050PV video
Both installations exhibit identical CPU issues - CPU1 or CPU2 will be running xorg at +80%.
I have tried both x86 and AMD64 bit versions of Ubuntu 8.04.
The systems run much slower than it should however everything seems to work fine.
On the first computer I tried the default nv video driver, then the Ubuntu 'latest' restricted driver and then I tried the latest nVidia driver as installed by Envy - all exhibited the same xorg race condition.
Something is definitely WRONG with this build.

I found the cause of the high CPU usage by xorg!
The very application I was using to watch CPU usage CAUSED xorg to consume +80% CPU usage.
The minute I shut down 'System Monitor' the CPU usage as reported by 'top' dropped to background levels.
So trhere is a problem BUT it isn't as serious as I first thought.
So all that must be done is to make sure 'System Manager' is not deployed on multi core CPUs.
