If it is handy for you to fwd me the "wrong" mail, it can also help me address the problem. One issue relates to "ERROR: modpost: "sysrq_mask" [drivers/tty/serial/serial_core.ko] undefined" is caused by modpost logging interface change, we had disabled this build false positive yestesday, and we will look for a solution for this soon.
