Hi Matt,

I've been reading through the netconsole driver in response to Greg's 
comments on this thread, and it is definitely more robust in terms of 
configuration and handling of network device events than the netoops 
driver I proposed.

What are your thoughts on extending netconsole with the same sort of 
semantics that are in the netoops patchset?

I'd still like to have blit-dmesg-to-the-network-on-oops semantics, 
which seems doable by having a per-target flag for streaming of console 
messages (enabled by default) and a flag to emit a structured full dmesg 
dump (disabled by default).

I'd be happy to change this patchset to modify the netconsole driver if 
you agree.

Thanks,

Mike Waychison
