However, this still is a bug and regression, so the > bugzilla entry remains open. Soerens original report was a 2.6.25 regression. And #10377 that was closed as a duplicate of #10117 was also reported as a 2.6.25 regression. #10117 seems to suffer from the common disease of people hijacking an existing bug, but Soeren's issue that was what was originally tracked in #10117 is (or was) a 2.6.25 regression. If other people have similar problems that already existed in 2.6.24 these are different issues that should be tracked in their own bugs. > Thanks, > Rafael cu Adrian -- "Is there not promise of rain?"
