Fetch a gigabyte's worth of data for the debuginfo RPM?  Um, I think
most users would not be happy with that, especially if they are behind
a slow network.  Including the necessary information so someone who
wants to investigate the oops, or having kerneloops.org pull apart the
oops makes more sense, I think, and is already done.

Something that would be **really** useful would be a web page where if
someone sends me an oops message from Fedora or Open SUSE kernel to
linux-kernel or linux-ext4, I could take the oops message, cut and
paste it into a web page, along with the kernel version information,
and the kernel developer could get back a decoded oops information
with line number information.

Kerneloops.org does this, so the code is mostly written; but it does
this in a blinded fashion, so it only makes sense for oops which are
very common and for which we don't need to ask the user, "so what were
you doing at the time".  In cases where the user has already stepped
up and reported the oops on a mailing list, it would be nice if
kerneloops.org had a way of decoding the oops via some web page.

Arjan, would something like this be doable, hopefully without too much
effort?
