2.6.30-rc7: Reported regressions from 2.6.29

Rafael J. Wysocki
2009-05-24T19:06:06Z

[NOTE:
Bug entries for which I know there are working patches get the
RESOLVED / PATCH_ALREADY_AVAILABLE status in the Bugzilla, which
makes it easier to check if the patches have been merged before sending
out the list. For this reason, please let me know of working patches
for any of the regression list items or (better) change the status of the bug
entries in case you know of a working patch (in which case please also add
a link to the patch to the appropriate bug entry).]

This message contains a list of some regressions from 2.6.29, 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 2.6.29, 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.
