Created attachment 433282 [details] VBox.log I have app-emulation/virtualbox app-emulation/virtualbox-additions app-emulation/virtualbox-extpack-oracle app-emulation/virtualbox-guest-additions app-emulation/virtualbox-modules installed here - each of version 5.0.20. These build (now) fine under the 4.6.0-rc6 kernel, but it crashes when I try to boot a Windows7 machine. Exactly the same image runs just fine with a 4.5 kernel and then Virtualbox 5.0.16. I get A critical error has occurred while running the virtual machine and the machine execution has been stopped. I've attached VBox.log and VBox.png Thanks for looking into it!

Hi, what's Guru Meditation and why is this bug fixed?
I can confirm this bug. Disabling CONFIG_X86_INTEL_MEMORY_PROTECTION_KEYS in kernel 4.6.0 does not help.
Upstream bug: https://www.virtualbox.org/ticket/15439 The same with linux-4.7.0_rc1. Compile fix for linux-4.7: https://www.virtualbox.org/raw-attachment/ticket/15459/VBoxNetAdp-linux.c.patch
https://www.virtualbox.org/changeset/61429/vbox "netadp: do not update trans_start for 2.6.31+" "This fix will be included in the next maintenance releases."

Well, it compiles but it dies nevertheless under Linux-4.7.0-rc3
As written on the upstream bug I can confirm enabling PREEMPT_NOTIFIERS in kernelconfig it runs stable. CONFIG_PREEMPT_NOTIFIERS is not available as a config option. Because of that it is only enabled with kvm in kernel enabled.
https://www.virtualbox.org/changeset/61806/vbox "VMM: bugref:8412, ticketref:15439: workaround for changed stack layout of Linux >= 4.6"
VirtualBox 5.0.24 (released 2016-06-28) This is a maintenance release. The following items were fixed and/or added: VMM: reverted to the old I/O-APIC code for now to fix certain regressions with 5.0.22 (bug #15529). This means that the networking performance with certain guests will drop to the 5.0.20 level (bug #15295). One workaround is to disable GRO for Linux guests. Main: when taking a screenshot, don't save garbage for blanked screens NAT: correctly parse resolv.conf file with multiple separators (5.0.22 regression) Storage: fixed a possible corruption of stream optimized VMDK images from VMware when opened in read/write mode for the first time Audio: imlemented dynamic re-attaching of input/output devices on Mac OS X hosts ACPI: notify the guest when the battery / AC state changes instead of relying on guest polling Linux hosts: fixed VERR_VMM_SET_JMP_ABORTED_RESUME Guru Meditations on hosts with Linux 4.6 or later (bug #15439) Solaris hosts: make the GUI work on Solaris 10 again (bug #15549) So, Please bump!
@Helmut Let this depend on bug 586630
This bug here has been fixed upstream in virtualbox 5.0.24. Compiling with linux-4.7 has also been fixed as far as I know. virtualbox-5.0.26.ebuild is in the tree (bug 586630 fixed) Older versions were removed from the tree. So I think this bug can be closed.
