Subject2.6.29-rc1: Reported regressions from 2.6.28
Date
[Notes:
* 2.6.29-rc1 is out so it's time for a regressions report. At the moment there
are not too many regressions from 2.6.28 listed.
* We've got quite a number of regressions from 2.6.27 reported against 2.6.28
final recently. For this reason, I'm going to continue reporting regressions
introduced between 2.6.27 and 2.6.28.
* Regressions 2.6.26 -> 2.6.27 won't be listed any more. There are only 6 of
them left and they don't seem to be urgent.
]

This message contains a list of some regressions from 2.6.28, 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 2.6.28, 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.
