Doc Text:
While back-porting the changes necessary to solve BZ#1086945, one related commit for the change was omitted. Two call sites were left using the old (now incompatible) notifiers calling parameters. One call site related to IPv6 setup and the other to a specific ATM driver. Users with a setup that relied on one of these call sites would see "Oops" messages during the boot process. In some cases, a system crash occurred. The missing changes from upstream are now included, which allow the boot process to continue normally.
