'qemumips64 + systemd + pam' results in being not able to login

Hi All,

Recently I noticed that if we start a systemd based qemumips64 target with 'pam' enabled in DISTRO_FEATURES, we could not login in successfully. After you provide username and password to the login prompt, the login prompt just comes up again.

Below is some error information.

Received SIGCHLD from PID 175 (login).
Child 175 (login) died (code=dumped, status=10/BUS) [email protected]: Child 175 belongs to [email protected] [email protected]: Main process exited, code=dumped, status=10/BUS

I've investigated this problem, but I could not find the root cause. Has any of you also seen the same problem?
Anyone has any idea what's going on here?

Best Regards,
Chen Qi
