Hi, everyone
I met a problem when debug the CM. the kernel version is 4.14.0-rc5
I am sure that the CM is ok on kernel 4.12
Have you met the same problem?

Is this perhaps a user space fault reported by the kernel? From kernel source
file arch/arm64/mm/fault.c:
pr_info("%s[%d]: unhandled %s (%d) at 0x%08lx, esr 0x%03x",
tsk->comm, task_pid_nr(tsk), inf->name, sig,
addr, esr);
You will need to identify what code in librdmacm caused this fault by using
tools that report a stack trace for the fault. Had you already considered to
run the application that uses librdmacm and that triggers this fault under gdb
or valgrind?
Bart.
