[This time it's without the accompanying reply messages, because there are
some MIME-related problems with them I have yet to fix and I didn't want to
defer sending the entire report because of them, given that we have some new
regressions caused by very recent commits.

First of all, commit 92c9d07507f0a90b64172bfede7e6fa845e8e66b, for which
there is a patch at http://lkml.org/lkml/2008/4/6/113, refers to undefined
symbols.

Second, http://bugzilla.kernel.org/show_bug.cgi?id=10410 is worrisome. It
looks like we have not understood the issue well enough, after all.

Apart from this, there seems to be a resume regression related to graphics
that's been causing some headaches to us recently. It's unrelated to the
recently reverted ACPI commit, but apparently is generic enough to affect
the users of both the ATI and Intel adapters, but only some of them.]

This message contains a list of some regressions from 2.6.24, for which there
are no fixes in the mainline I know of. If any of them have been fixed already,
please let me know.

If you know of any other unresolved regressions from 2.6.24, please let me know
either and I'll add them to the list. Also, please let me know if any of the
entries below are invalid.

From BZ:

“It looks like 2.6.24 is good, I guess I'll start bisecting....”

there have been two bridge-related patches between v2.6.24-rc6..v2.6.24:

2dc2f20... [NETFILTER]: bridge-netfilter: fix net_device refcnt leaks
2948d2e... [NETFILTER]: bridge: fix double POST_ROUTING invocation

Maybe it helps to try 2dc.
Not anymore a 2.6.25-rc issue it seems?

You seem to be confused by the fact that the submitter typoed
"2.6.24-rc6" instead of "2.6.25-rc6" in his bug report?

Q: Has a consensus been made already whether or not to release the next
kernel version with still pending/unresolved regressions?

Heh. We've always had some pending/unresolved issues, and I think that as
out tracking gets better, there's likely to be more of them. A number of
bug-reports are either hard to reproduce (often including from the
reporter) or end up without updates etc.

So yes, I do end up releasing with pending issues, although I often try to
get a gut feel for what kind of severity we're talking about and not
release with *big* pending issues.

This one is very difficult to verify. It happened exactly once in
now 20 days... I'll be away from the box until the weekend,
when I'll compile whatever kernel-of-the-day with Ilpo's fix
on top, if it isn't in mainline by then, and... well, keep the
torrents alive with an eye on the kernel logs.

Not sure what's the best thing to do with such a hard to
reproduce issue. Perhaps marking it fixed by Ilpo's patch,
and if it pops up again file a new bug linking it to the entry
in bugzilla ?

Well, I will close it as "unreproducible". You can always reopen it if the
problem occurs again.

Marcelo fixed this a few days ago; I'll post my 2.6.25 queue soon.

Can you bcc subsystem maintainers with entries on this list? Or perhaps
those that opt-in?

In the future I will send an automatic reply message to the report for each
regression listed and the CCs will be added to these messages. This is still
under development, though, so please be patient.

Do a git bisect for this as the report isn't getting much attention?
