Subject2.6.33-rc5: Reported regressions 2.6.31 -> 2.6.32
Date
[NOTES:
* This is worrisome. Regressions from 2.6.31 are still being reported and we
are not fixing them. Even the ones that have been bisected don't seem to
be taken care of.]

This message contains a list of some regressions introduced between 2.6.31 and
2.6.32, 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 2.6.31
and 2.6.32, 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.
