Someone mentioned this, and I did not see any response. Please show how a legitimate real bonding configuration can be created, reproduce a stray memory access, and therefore potentially cause a crash. Using various debugging features of the kernel should allow you to trigger an assertion quite easily if this bug really exists. -- To unsubscribe from this list: send the line "unsubscribe linux-rdma" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
