I updated my work desktop to kernel-3.10.0-1062.4.1.el7.x86_64 yesterday as I was leaving. This morning booted into that new kernel I was unable to login using my common access card.  Rebooted in the previous kernel (3.10.0-1062.1.2.el7.x86_64) and smart card login works fine. Anyone else seeing any similar problems?  I haven't had time to dig deeply into the logs yet but I did a bunch of pcscd restarts overnight, about once per hour according to monit.

Hi Stephen, I never used pcscd and card login and I don't know how it works. Without any type of error/message/warning from system logs I cannot help much but I will try. I would ask:

1) You need a kernel module to use your drive? 2) If yes to the previous, this modules was compiled manually(a) or is shipped by centos(b)? 2a) if compiled manually, you need to compile it again because kernel local version is changed to -1062.1.2.el7.x86_64 so the previous module will not load (you can try to load using --force-modversion). This happens to me when I update the kernel and the module that manage my waterblock led does not work anymore. 2b) Check if you module is loaded and if not try to load it and check again.

3) Can you boot your workstation and make the login without the card reader? If yes you could check what differs from the previous and the new kernel when running pcscd (maybe using strace or similar tool).

5) What report logs? This is the first thing that I will check before try actions and before ask in ML and if I can't solve then ask help reporting errors found. Maybe someone could help you with more detailed informations.

My 2 Cent(O)s.
