Public bug reported: I'm building custom router based on Ubuntu Server. With bridging/routing enabled I've encountered kernel panic (several times in row with neither visible reason nor specific timings) in br_nf_pre_routing_finish_bridge with atl1c driver loaded.
The bridge br0 consists of 1 port (eth0), which is the following network card: 05:00.0 Ethernet controller: Qualcomm Atheros AR8151 v2.0 Gigabit Ethernet (rev c0) It is driven by atl1c module. The network behind this card is NAT'ed. Kernel panic photo and lspci output are attached to this report. With different network card everything works OK.
