Adrian Bunk posted a couple lists of known regressions that found their way into the 2.6.21-rc1 kernel [story] since the release of the 2.6.20 kernel [story]. Adrian notes that his lists only include bugs that are not yet fixed in Linus' -git tree. In an updated version of his lists he included 19 known regressions, including links to bugzilla or the appropriate mailing list discussion thread. The lists track who submitted the bug, who is currently handling it, who caused it if known, a link to a patch that fixes the problem if any, and the current status.
