[Note to bug reporters: If you can, please always add
kernel-testers@xxxxxxxxxxxxxxx to the CC lists of your reports, as that will
help to filter them out of the other LKML traffic. Also, if you report a
regression, please add '[regression]' or something similar to the subject.]

This message contains a list of some regressions from 2.6.25, 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 2.6.25, 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.
