The problem is that most times these bugs aren't fixed by a trivial
patch. Quite often, "fixing" the bug was done by upstream kernel, at the
expense of major rewrites to the subsystem in question (acpi and ata are
good examples of this). One good reason we wouldn't backport such a
change is that in a lot of cases, we have no idea what fixed it (just
that the bug was reported fixed in linux 2.6.x, and so we accept that it
The upstream kernel also has a policy of not retaining compatibility
code. So it's not like we can grab the ata subsystem from 2.6.15, and
drop it into our 2.6.12 kernel.
Even if we can identify the patch(es), and yes, they have fixed your
problem, this code is so new, we don't know if it breaks things for
Bottom line is generally, we only consider regressions to be critical
for hardware failures (works in hoary, not in breezy). Even then, after
the dist has been released, there's only slight changes that things will
get fixed, assuming it is possible.
I am hoping that this improves post-dapper. I went through the kernel
bug list, and am busy trying to get it manageable. Once it is at a point
where maintaining the bugs isn't such a chore, then hopefully we can
revisit our policy on these sorts of things.
