[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.
