I'm not sure I'd classify them as "unpopular" but I definitely agree
they go unnoticed.  That's why I'd at least like them to test with the
most recent kernel to verify if their bug has been fixed or not.  If
not, it's likely the issue may exist upstream I imagine so this may be a
scenario to forward bugs upstream.

At least for the 2.6.17, 2.6.20, and 2.6.22 bugs we are closing them as
"Won't Fix" with a request to test the latest release.  We're then
automatically opening and setting the linux task to Incomplete until
they test and provide feedback.  So these should stay off your radar
until they're actually tested and confirmed to exist against the latest
release.

For 2.6.15 bugs I proposed a slightly different process just because it
was an LTS release.  But I'd be fine with using the same procedure above
that I'd use with the other non-LTS kernels.

Agreed.  I know your guys' time is best spent focusing on the bugs which
affect the current release.  However, I don't think that means we should
just ignore legitimate kernel bugs reported against older kernel
releases but may still exist in the current one.

Hopefully by setting the bugs to "Won't Fix" for the older kernels and
"Incomplete" for the recent kernel, they should stay off your radar
until they are confirmed to exist in the latest release.

Thoughts on this?

Thanks for the feedback already,
Leann
