Configure /etc/sysconfig/netdump 2. /etc/init.d/netdump start 3. Additional info:
netdump is unsupported on x86_64; the netconsole driver included in Fedora is not compatible with the user-space netdump code, which expects a completely different netconsole module (i.e. the version that is included with RHEL2.1 and RHEL3. But even if the old netconsole module were in place, it would reject any attempt to use its netdump facility on an x86_64. That all being said, support for x86_64/netdump is in the works for a future release.
