This email lists some known regressions in 2.6.19-rc5 compared to 2.6.18.

If you find your name in the Cc header, you are either submitter of one
of the bugs, maintainer of an affectected subsystem or driver, a patch
of you caused a breakage or I'm considering you in any other way possibly
involved with one or more of these issues.

Due to the huge amount of recipients, please trim the Cc when answering.
