Dell is working with the Linux community and Linux vendors to resolve this issue. To avoid possible IERRs during X Window System startup, perform the following steps: 1 Edit the XFree86 configuration file /etc/X11/XF86Config and search for "ServerFlags". • If the ServerFlags section does not exist, add the following lines to the configuration file: Section "ServerFlags" Option "PciOsConfig" "1" EndSection • If the ServerFlags section does exist, add the following line to that section: Option "PciOsConfig" "1" 2 Search for "Device" and, within the Device section, add the following option line: Option "NoINT10" These changes prevent a race condition with the kernel when the X Window System accesses the PCI Configuration registers. Issue Running the X Window System on the Dell PowerEdge 6800 and 6850 Due to the increased number of available PCI devices on the Dell™ PowerEdge™ 6800 and 6850, the X Window system may not start successfully with the default settings chosen by the Red Hat® installer. To resolve this issue, either change the Driver setting in /etc/X11/XF86Config from radeon to vesa, or update XFree86 to 4.3.0-69 or later through the Red Hat Network.
