[NOTES: * This report has been delayed, because I had to go through all of the entries and filter out the fixed ones, invalid ones etc. Of course, I might have missed some, but hopefully not too many. * E-mail reports from the last 7 days are not included.] This message contains a list of some post-2.6.33 regressions introduced before 2.6.34, for which there are no fixes in the mainline known to the tracking team. If any of them have been fixed already, please let us know. If you know of any other unresolved post-2.6.33 regressions, please let us know either and we'll add them to the list. Also, please let us 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.
