+After upgrade qemu to 5.0.0-0.3.rc2.fc33 the virtual machine with Windows 10 after a while starts to work very slowly
+
+Description of problem:
+
+After upgrade qemu to 5.0.0-0.3.rc2.fc33 the virtual machine with Windows 10 after a while starts to work very slowly
+
+I created the virtual machine with Windows 10 with the following config:
+- 1 CPU
+- 2GB RAM
+- With network access
+
+I launch there a web browser there with flash content. 
+And usually, the system (Windows 10) does not work there for more than an hour.
+When the system starts to work very slowly it doesn't respond to "Reboot" and "Shut Down" commands. Only works "Force Reset" and "Force Off". But when I reboot the system with "Force Reset" it usually stuck at boot at the Windows splash screen. https://imgur.com/yGyacDG
+
+The last version of qemu which not contain this issue is 5.0.0-0.2.rc0.fc33
+
+
+
+When VM starts work very slowly System interrupts in Windows Task Manager eats up 99% of all CPU resources.
+
+
+Please try this patch series: https://lists.gnu.org/archive/html/qemu-devel/2020-05/msg02728.html
+
+Unofficial x86_64 build of v5.0.0 with those 2 patches for Arch is here: [1].
+
+[1] https://download.opensuse.org/repositories/home:/post-factum/Arch/x86_64/
+
+I confirm that with patches https://lists.gnu.org/archive/html/qemu-devel/2020-05/msg02728.html Win 10 in QEMU working already more than 24 hours without issue.
+
+The patches mentioned in the previous comments have been released with QEMU v5.1, so I'm marking this bug as fixed now. If you still have problems, please open a new ticket.
