Hi Dave!
It can happen that crash does not extract the correct Linux version string
from vmlinux. Therefore the comparison with /proc/version fails at startup:
WARNING: /usr/lib/debug/lib/modules/2.6.17-1.2519.4.21.el5/vmlinux
and /proc/version do not match!
Crash gets the release string by searching strings in vmlinux. Something
like:
>> strings vmlinux | grep "Linux version"
>`0Linux version 2.6.17-1.2519.4.21.el5 ...
On our system the string does not start with "Linux...", but with "0Linux...".
Therefore crash assumes a wrong version string. To fix this, we should skip the
leading "0":
