[ANNOUNCEMENT: Maciej Rutecki has generously volunteered to work on the tracking of kernel regressions with me, so now there are two people doing this and I'm going to call us "the tracking team". Please be friendly to Maciej, he's doing his best to help. If you have any information about kernel regressions you want to share with us, please feel free to contact Maciej as well as me.] This message contains a list of some regressions from 2.6.32, 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 regressions from 2.6.32, 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.
