Description of problem:
Starting netdump gives:

FATAL: Error inserting netconsole
(/lib/modules/2.6.5-1.326.alexk/kernel/drivers/net/netconsole.ko):
Unknown symbol in module, or unknown parameter (see dmesg)

Looking more closely its trying to do:

modprobe netconsole magic1=0x4b0f108c magic2=0x67ed9511 dev=eth1
netdump_target_ip=0xC2D95A03 netlog_target_ip=0xC2D95A03
source_port=6666 netdump_target_port=6666 netlog_target_port=6666
netdump_target_eth_byte0=0x00 netdump_target_eth_byte1=0x08
netdump_target_eth_byte2=0xC7 netdump_target_eth_byte3=0x2B
netdump_target_eth_byte4=0x62 netdump_target_eth_byte5=0x37
netlog_target_eth_byte0=0x00 netlog_target_eth_byte1=0x08
netlog_target_eth_byte2=0xC7 netlog_target_eth_byte3=0x2B
netlog_target_eth_byte4=0x62 netlog_target_eth_byte5=0x37 mhz=2193

which doesn't seem to be the format the driver wants at all:

parm:           netconsole:
netconsole=[src-port]@[src-ip]/[dev],[tgt-port]@<tgt-ip>/[tgt-macaddr]


Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
1. Configure /etc/sysconfig/netdump
2. /etc/init.d/netdump start
3.

Comment 1 Dave Anderson 2004-04-20 12:25:03 UTC
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.
