[NOTES:
* Sorry for the delay, I had to take care of my own bugs first.
* Some of the bugs below are fixed, but I wasn't able to track the fixes down.
* There probably are some duplicates (mostly in the DRI area), but I wasn't
100% sure.]

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.
