The hardware has two message control interfaces, but the code only uses the first one. So on SMP the following can be observed: CPU0 CPU1 rx_poll() write IF1 xmit() write IF1 write IF1 That results in corrupted message object configurations. The TX/RX is not globally serialized it's only serialized on a core. Simple solution: Let RX use IF1 and TX use IF2 and all is good.
