We haven't fixed all of them yet and they're still being reported. Also, they need to be fixed as well as those introduced later (although they may be considered as "less important"). Quite frankly, I don't know how this is going to work out, but I thought it's worth trying. Enjoy! ;-)] This message contains a list of some regressions introduced between 2.6.26 and 2.6.27, 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 introduced between 2.6.26 and 2.6.27, 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.
