[Notes:

 * Quite a number of new regressions from 2.6.30 has been reported during
   the last three weeks.

 * The number of unresolved regressions 2.6.30 -> 2.6.31 is now the second
   highest ever.]

This message contains a list of some regressions introduced between 2.6.30 and
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 introduced between 2.6.30
and 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
