Bug description:
  In xenial, pcscd CPU utilization occasionally goes haywire:

    PID USER      PR  NI    VIRT    RES    SHR S  %CPU %MEM     TIME+ COMMAND                                                                                                                                       
  27404 root      20   0  384264   4992   2228 S 100.3  0.0  75:39.03 /usr/sbin/pcscd --foreground --auto-exit                                                                                                      

  I get this about once a day since installing xenial. I can't quite
  connect it to any specific event on the system, it just seems to
  happen sporadically -- fan turns on, I run top, and there it is again.

  Never had this issue on same hardware incl. smartcard with trusty.

  I wonder if it might be this? https://bugs.debian.org/cgi-
