Invalid bug check hit, fixed upstream: http://cgit.freedesktop.org/xorg/xserver/commit/dix/devices.c?id=6a848122def0f2a439e21c50f22814db11760132
Hey Jana, Fantastic! Thank you for the update.
Yes, I can confirm that this fixes the problem. Or at least that build 1.15.99.903 (which includes the above fix) does not exhibit this issue anymore with PV guests.
This bug appears to have been reported against 'rawhide' during the Fedora 22 development cycle. Changing version to '22'. More information and reason for this action is here: https://fedoraproject.org/wiki/Fedora_Program_Management/HouseKeeping/Fedora22
Fedora 22 changed to end-of-life (EOL) status on 2016-07-19. Fedora 22 is no longer maintained, which means that it will not receive any further security or bug fix updates.
