FC3 Xorg Savage Temporary Freeze

[rhmail at hacksaw.org]

I upgraded my laptop (an HP Pavilion N5210) to FC3.

I had some trouble with the X set up during installation, so I went text 
install, and proceeded. After a bit of a trial, it got there, and looked all 
right.

X soon proved a bit of a problem. At first, I'd start it, and it'd work for a 
minute, then freeze, and lock the machine.

I forced SWCursor on (this was needed in previous X installations on this 
machine), and that didn't help the freezing. Then I tried "ShadowStatus on".

This stopped the lock up, but it still freezes for perhaps 10 seconds, and 
then comes back.

I ran top over an ssh connection to my desktop. What happens is the X server 
eats up 99.9% of the CPU for a few seconds, then suddenly backs off, and 
things proceed.

Seems like a race to me.


The bug is reproducable by a number of things. One that seems to work 
consistently is to start up2date-config, and flip through the tabs.

Scrolling quickly in firefox is another one, though it's a bit less consistent.

I have the most recent version of the xorg release on the machine 
(xorg-x11-6.8.1-12.FC3.21 and friends).

Here's my xorg.conf:
