Doc Text: |
When the netconsole module was configured over bridge and the "service network restart" command was executed, a deadlock could occur, resulting in a kernel panic. This was caused by recursive rtnl locking by both bridge and netconsole code during network interface unregistration. With this update, the rtnl lock usage is fixed, and the kernel no longer crashes in this scenario.
