|Red Hat Enterprise Linux 4: Installation Guide for the IBM® S/390® and IBM® eServer™ zSeries® Architectures
This appendix discusses some common installation problems and their solutions.
A signal 11 error, commonly know as a segmentation fault, means that the program accessed a memory location that was not assigned.
If you receive a fatal signal 11 error during your installation, it is probably due to a hardware error in memory on your system's bus. A hardware error in memory can be caused by problems in executables or with the system's hardware. Like other operating systems, Red Hat Enterprise Linux places its own demands on your system's hardware. Some of this hardware may not be able to meet those demands, even if they work properly under another OS.
Ensure that you have the latest installation updates and images from Red Hat. Review the online errata to see if newer versions are available. If the latest images still fail, it may be due to a problem with your hardware.
