netconsole.ko module for 2.6.12 firmware kernel does not want to load
Hi,
I've followed the wiki crosscompile guide and have compiled a netconsole module to be able to trace my ffp-reload problems (C1 hardware anyone?).
But when I try to load it, it exits with error:
root@Tiromancino:/wd/DNS323# /usr/sbin/insmod netconsole.ko netconsole=@/,@192.168.33.1/
insmod: error inserting 'netconsole.ko': -1 Unknown symbol in module
root@Tiromancino:/wd/DNS323#
dmesg shows:
netconsole: Unknown symbol netpoll_parse_options
netconsole: Unknown symbol netpoll_setup
netconsole: Unknown symbol netpoll_queue
netconsole: Unknown symbol netpoll_send_udp
netconsole: Unknown symbol netpoll_cleanup
Any idea?
My first guess is that stock 2.6.12 firmware won't be able to load the module because of missing configure options, am I right?
Fred

Maybe. But it's also possible that you need to load another module first. Try to find which .c file defines these functions, and if there is a corresponding .ko file.

Re: netconsole.ko module for 2.6.12 firmware kernel does not want to load
thanks for the tip but I think I'm screwed 
:
./net/core/netpoll.c:EXPORT_SYMBOL(netpoll_parse_options);
./net/core/netpoll.c:EXPORT_SYMBOL(netpoll_setup);
./net/core/netpoll.c:EXPORT_SYMBOL(netpoll_cleanup);
./net/core/netpoll.c:EXPORT_SYMBOL(netpoll_send_udp);
./net/core/netpoll.c:EXPORT_SYMBOL(netpoll_poll);
./net/core/netpoll.c:EXPORT_SYMBOL(netpoll_queue);
Seems like it should be compiled inside the kernel...
Too bad.
