Ticket #9760 (closed defect: obsolete)
VirtualBox deadlocks host system while running guest.

Description (last modified by frank) (diff)
When I run a Guest OS, such as Ubuntu, Windows 7, Windows 8 and even others, the OS will, at random, freeze. When I go to reset the VM that also fails. If I open up Process Explorer and kill the VirtualBox Process there is one thread left over which sits in a "Wait:WrResource" state. The longer the system is left with this thread in a deadlock the more the other programs on the host OS are affected. Also once VB has deadlocked, the GUI manager can't be opened anymore if it is closed.
I tried earlier versions of VirtualBox, all the way back to 3.2.12 and the problem exists in them as well. The best version seems to be 3.2.12 where the Guest will run for quite some time before experiencing this issue.
The only way to get rid of the deadlocked thread is to use forcefully reset the Host Machine, Windows cannot kill it.
Steps to Reproduce
- Start VM
- Use it for a bit (Some times on boot too)
- It will lockup
- Try to reboot host and it will sit at the Shutdown Screen
