The reader lights will flicker for about 5 minutes until they finally stop. No other issues are seen with the system during this time. Upon looking at /var/log/syslog, the errors listed in the attachment are visible as it appears gsd-smartcard is in a loop of restarting and crashing following an error. /var/crash contains two files from the crash loop, _usr_libexec_gsd_smartcard.1000.crash and _usr_libexec_gsd_smartcard_127.crash Eventually the crashes seem to stop and the light stops flickering, but a logout and log back in will restart the issue again, as will rebooting the machine. Re-plugging the device while logged in does not seem to cause it to start the crash loop again. To complete the standard questions: 1. I logged into my computer and saw error messages 2. I expected the smart card to be ignored if there was a card inserted that was unexpected or incompatible with the gnome settings daemon 3. I encountered several crash reporter messages upon logging in, which seem to have come from the gsd-smartcard program
