I tried to replicate this under qemu on debian unstable with pinentry
1.1.0-4 and did not see the behavior you're describing.
Here's what I did:
- launch a debian x86_64 qemu/kvm-based guest
- as a non-privileged user, connected to it via ssh, ran "pinentry-tty"
-- in that console, i typed "getpin" (got a prompt "PIN: ")
- while waiting on that prompt, as the superuser, i did "systemctl
suspend"
- the qemu guest froze, and from its monitor port, i ran
"system_wakeup"
- the system unfroze, and i was able to continue entering my PIN, and
pinentry-tty behaved as expected.
- there was nothing in the dmesg to indicate any problem.
Are you able to help replicate this?
