Date: Wed Sep 26 2007 - 19:13:59 EST


This message lists some known regressions from 2.6.22 for which there are
no fixes in the mainline that I know of. If any of them have been fixed
already, please let me know.

If you know of any other unresolved regressions from 2.6.22, please let me know
either and I'll add them to the list.
