I have something particular I am testing now (probably a nouveau related crash) that crashes for netconsole gets loaded (though I tried to add it to the initramfs to get it loaded fairly early). I am not sure if it will be early enough even if it is built in. I won't know until sometime tomorrow. But if it does get loaded early enough to handle video card related stuff, it seems like it be worth having built into debug kernels.
The crash appears appears to be happening too early to send netconsole output even when netconsole is builtin to the kernel.
Also I may have been wrong about it not being built in, as I am not finding a netconsole.ko in /usr/lib/modules. The config file for Fedora normally has: config-3.15.0-1.fc21.i686+PAE:CONFIG_NETCONSOLE=m config-3.15.0-1.fc21.i686+PAE:CONFIG_NETCONSOLE_DYNAMIC=y
But maybe enabling the dynamic feature forces it to be built in now?
It looks like I'll need to try something else to get the beginning of the traceback from the crashes.
