A Kernel oops leaves Ubuntu 16.04 unusable when a network bridge is brought down on a HPE 530SFP+ 10GBit NIC that uses bnx2x as a driver. This error does not appear in Ubuntu 14.04 however.
The error is reproducible whenever issuing the commands "shutdown", "service networking stop" or "brctl delbr br0". Manually creating the bridge and subsequently bringing it down results in the same error.

A Kernel oops leaves Ubuntu 16.04 unusable when a network bridge is brought down on a HPE 530SFP+ 10GBit NIC that uses bnx2x as a driver. This error does not appear in Ubuntu 14.04 however.
The error is reproducible whenever issuing the commands "shutdown", "service networking stop" or "brctl delbr br0". Manually creating the bridge and subsequently bringing it down results in the same error.

A Kernel oops leaves Ubuntu 16.04 unusable when a network bridge is brought down on a HPE 530SFP+ 10GBit NIC that uses bnx2x as a driver. This error does not appear in Ubuntu 14.04 however.
The error is reproducible whenever issuing the commands "shutdown", "service networking stop" or "brctl delbr br0". Manually creating the bridge and subsequently bringing it down results in the same error.
