Comment 65 for bug 1866870

Hello!
Unfortunately the bug has apparently reappeared. I have a Windows 10 running in a VM, which after my today's "apt upgrade" goes into pause mode after a few seconds of running time.

Tail output of my /var/log/libvirt/qemu/win10.log
char device redirected to /dev/pts/1 (label charserial0)
