Ok, I see. Right after a suspend/resume, pcscd goes to 100% CPU. So this is
related to suspend/resume.
The output generated after the suspend/resume is:

I setup a laptop (old MacBook Pro) using Debian stable (plus pcsc-lite from
unstable) and I can't reproduce the problem.
Suspend/resume works great on this machine and pcscd is still working correctly
after the resume.
I then upgraded the system to Debian testing and pcscd is still working
correctly.
So I can't reproduce your bug for now.
Bye
