[Notes:
* Here's the first summary report of known regressions from 2.6.31. There's
not too many of them at the moment, which is nice.
* We're still getting quite a number of reports of regressions from 2.6.30 and
it's been that way since 2.6.31 was released. For details please see the
summary report of regressions 2.6.30 -> 2.6.31 that will follow shortly.]
This message contains a list of some regressions from 2.6.31, 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 2.6.31, 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.
Each entry from the list will be sent additionally in an automatic reply to
this message with CCs to the people involved in reporting and handling the
issue.

If you add one more entry say "Suspected commit :" then it will be great
and will solve regressions much faster. You can request submitter to
submit 'suspected commit' by git bisect and also specify git bisect
links like : (for more information about git bisect check
http://kerneltrap.org/node/11753)

I disagree. A reporter should only be asked to bisect (using git or
other tools) /if/ a developer determined that bisection may speed up the
debugging process or is the only remaining option to make progress with
a bug.
It would be wrong to steal a reporter's valuable time by asking for
bisection before anybody familiar with the matter even had a first look
at the report.
Remember:
- Not all bugs can be economically narrowed down by bisection.
- Bisection requires skills, rigor, and time.
- Alas there are considerable sections in our kernel history which
are not bisectable.

In fact I add the "First-Bad-Commit" annotation where there is a bisection
result or it's possible to fix things by reverting a specific commit.

Sorry for the late answer - I had ISP troubles.
The above bug entry should NOT be listed, because the problem
was fixed in 2.6.32-rc1, and Jens Axboe pointed me the exact
commit, which solves my problems (it was raid related).
Thanks,
