Hi, the fix for this is: commit 8172012df1d981ef1934ede430c4936eae50e5f7 Author: Srinivas Aji <Aji_Srinivas@xxxxxxx> Date: Thu Jul 3 22:45:03 2008 +0530 Fix crash when BPDU received on bridge if. We could receive non STP BPDU's on bridge interface, or even STP BPDUs if STP is off for the bridge. The crash is avoided by checking for bridge interface and not processing further in that case.
