[El Capitan] Kernel Panic on VM shutdown

[steinharts]

I had a kernel panic while shutting down a windows 8.1 virtual machine. Attached the logs.

Same happens to me on OS X El Capitan with a Windows7 guest.

Also confirming this happens in El Capitan with a Windows 7 guest. I think it's actually happening for any guest for me as long as I connect at least one USB device.

Version 5.0.12 r104815. Host = El Cap. Guest = Windows 7. Extension pack installed: Oracle_VM_VirtualBox_Extension_Pack-5.0.12-104815.vbox-extpack. Guest additions also installed. Kernel panic occurs when attempting to shutdown while there is an existing USB connection. No kernel panic on shutdown without an existing USB connection. Kernel panic also occurs when attempting to disconnect existing USB connection (without shutdown).

Same happens for me, panic on shutdown. Seems related to using USB. Version 5.0.12 r104815 w/extensions and additions installed. Host: El Capitan. Guest: Window 10. Top of panic log below.

We would need to have the crash dump available to find the reason for this panic.

Could you also test the most recent 5.0 Mac OS X test build (>= 105008) and test if it makes any difference? Thank you!

Replying to frank:

Now running Version 5.0.13 r105025 and it seems fixed! Until this version, ever since upgrading to El Capitan, I was getting 100% kernel panics on shutdown after using USB. Looking good, thanks.

[Frank Mehnert]

Thanks for testing! The fixes are part of VBox 5.0.14. Please reopen if still relevant with VBox 5.0.14.
