Huh? The bugzilla just tracked a bug reported to lkml. The very
description of the bugzilla says:

Subject : v2.6.24-rc2-409-g9418d5d: attempt to access beyond end of device
Submitter : Thomas Meyer <thomas@m3y3r.de>
References : http://lkml.org/lkml/2007/11/13/250

so no, it was evidently not "hidden in bugzilla for ages" - all the
important action happened on lkml.

again, this bugzilla entry originated from lkml. I did ping the bugzilla
because i saw that the suspected commit's author was Cc:-ed already. Why
should every bug reporter and debugger be fully aware of the absolutely
SILLY little details and preferences of maintainers about how and whom
to report bugs?

YOU made the workflow fragile in the first place, by going away to
linux-scsi and ignoring lkml reports. Or in your own words, in the
bugzilla, comment #9:

http://bugzilla.kernel.org/show_bug.cgi?id=9370#c9

Erm, actually no ... this is the first I've heard of it, except as a
passing question from matthew. It's usually safe to assume if it's
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
not on linux-scsi I haven't seen it.
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

that's fundamentally flawed. For testers there should be only one,
simple as possible rule:

"if you have a problem with the Linux kernel, then report it to lkml"

[ or report it to your distro or bugzilla.kernel.org, where it will be
propagated towards lkml by others. ]

not to "report it to one of the 100+ lists listed here - good luck
getting it right":

yes, there can be other lists and mails, so this isnt a rigid rule in
any way, but the _default_ is for maintainers of major subsystems to be
aware of all bugs related (or suspected to be related) to their
subsystems reported to lkml. Not to be dragged on to lkml kicking and
screaming ;-) lkml isnt just for the core kernel, it's for the _whole_
kernel.
