I'm not the person Linus was addressing, but I've had plenty of oopses with 2.2.1 - 2.2.10 and have not sent any in.
So far as I know there are only two ways to capture the data related to an oops. Write it down with a pencil, or capture it via a serial port on another machine. The first seems too prone to errors, and the second just isn't realistic for me and my cluster of machines. Too many serial cables going every which way. Or maybe I'm just lazy.
I have a setup which oopses in 5 minutes to a few days when compiled with SMP support. The identical source compiled without SMP runs forever as far as I can tell.
Since all things have previously be discussed on this list, I'm going to let my linux "newbieism" show by asking for a feature which has undoubtably been asked for before and has undoubtable been shot down for very legitimate reasons.
I would like my oops'ing systems to send the oops to another system via an ethernet interface. How about a UDP packet? Nice connectionless protocol. Compile the MAC/IP address into the kernel. Opps occurs, build the UDP packet with the measly 2K oops message in it and send.
