[Notes: * Some new regressions from 2.6.28 have been reported since the release of 2.6.29, so here's an update of the regression list. * I could have missed some fixes due to the large amounts of stuff merged recently. Please have a look at the list and let me know if I can drop anything from it. * I'm not going to track regressions from 2.6.27 any more. * Next time I'll list regressions from 2.6.29 (after 2.6.30-rc1) and new regressions from 2.6.28 (if any) will be appended to the list below as "regressions introduced between 2.6.28 and 2.6.29".] This message contains a list of some regressions from 2.6.28, 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 from 2.6.28, 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.
