Section D.2:Trouble During the Installation
D Troubleshooting Your Installation of
Red Hat Linux
This appendix discusses some common installation problems and their solutions.
D.1 You are Unable to Boot Red Hat Linux
D.1.1 Is Your System Displaying Signal 11 Errors?
If you receive a fatal signal 11 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 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.
Check to see if you have the latest installation and supplemental boot diskettes 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. Commonly, these errors are in your memory or CPU-cache. A
possible solution for this error is turning off the CPU-cache in the BIOS. You could also try to swap
your memory around in the motherboard slots to see if the problem is either slot or memory related.

D.2 Trouble During the Installation
D.2.1 Partition Creation Problems
If you are having trouble creating a partition (for example, a root (/) partition), make sure you are
setting its partition type to Linux Native.
D.2.2 Are You Seeing Python Errors?
During some upgrades or installations of Red Hat Linux, the installation program (also known as
Anaconda) may fail with a Python or traceback error. This error may occur after the selection of
individual packages or while trying to save the upgrade log in /tmp. The error may look similar to:
Traceback (innermost last):
File "/var/tmp/anaconda-7.1//usr/lib/anaconda/iw/progress_gui.py",
line 20, in run
rc = self.todo.doInstall ()
File "/var/tmp/anaconda-7.1//usr/lib/anaconda/todo.py", line 1468, in
doInstall
