- XFree86 produces error reports very much like the kernel output. For
- example, this is a sample XFree86 report.

- All you need is a small adjustment to the EIP line (ksymoops expects
- kernel format with a bracketed address) plus something that looks like
- a System.map but is actually generated from the failing program and you
- can use ksymoops on XFree86 programs.
- Generate the map by
- objdump -T /usr/X11R6/bin/failing_program |
- fgrep -v '*UND*' |
- awk '{print $1, $2, $NF}' > map
- Feed the oops with an adjusted EIP plus the map to ksymoops and send
- the decoded result to the person responsible for the failing program.
- sed -e 's/(eip: *)([^ ]*)/1[<2>]/' < oops | ksymoops -VKLO -m map
