I'm having some problems after a memory upgrade.
I have a HP DL380 G5 server with an Intel 5130 CPU, 2GB RAM, running Fedora Core 5 x86_64, standard kernel 2.6.17.
uname -a
Linux servername 2.6.17-1.2174_FC5 #1 SMP Tue Aug 8 15:30:44 EDT 2006 x86_64 x86_64 x86_64 GNU/Linux
Everything works fine like this. However, when I put in another 2GB of RAM, X takes up all the CPU on startup. If I SSH in, things are very slow, but I can "kill -9" the process. This doesn't actually kill it completely (still appears in list of processes on 100% CPU), but it makes the box usable again. Presuambly after killing it has only locked up one of the cores.
Things to note: the RAM is physically fine and installed properly (tested by running the box in memory mirroring mode). Box seems to be fine at runlevel 3.
The graphics card is an (onboard) ATI ES1000. I am guessing the problem is something to do with the driver for this - xorg.conf specifies the "radeon" driver. I have attached the X log file, which doesn't seem to contain any clues for me at least!
I'm not exactly a Linux guru, so any help would be much appreciated! Even where to start debugging further would be useful.
EDIT: More research suggests the problem might well be with the video driver. I have xorg-x11-drv-ati.x86_64 version 6.5.8.0-1 installed and this seems to be the latest package available. Can I get a newer version of this for FC5 from anywhere? I notice there is a version 6.6 package for FC6.
Thanks.
