Hi;
I'm attempting to port VirtualBox 6.0.8 to FreeBSD. I managed do get it
working perfectly up to
11.3-STABLE-amd64-r359971.
After an svn up to 11.4-PRERELEASE-r360676M, VirtualBox 6.0.8 no longer
works. Bringing world+kernel back to 11.3-STABLE-amd64-r359971 makes it
work again, despite whatever ports I've got installed on my machines. This
was tested on 2 physical machines (desktop and laptop) and it is true for
both.
When starting a VM on 11.4-PRERELEASE-r360676M, the VM console window shows
up for 2 seconds and vanishes. Tha VM log shows this:
--------------------------------------------------------------------------------------------------------

--------------------------------------------------------------------------------------------------------
This is the same error that shows when trying to run it on
12.1-STABLE-amd64-r359985 by the way.
I am no wiz. And on top of that, VBox is extremely complex but I don't
think that the problem lies on the kernel or on vbox kernel modules. They
all load correctly and without errors on both 11.4-PRERELEASE-r360676M and
12.1-STABLE-amd64-r359985.
What looks like (to my poor lame eyes) is that some revision change in
userland "broke" the connection between vbox and its modules/drivers.
So my quest is to try to pinpoint the changes between
11.3-STABLE-amd64-r359971 and 11.4-PRERELEASE-r360676M that made VirtualBox
6.0.8 stop working, and I was wondering if anyone here could give me some
direction on how to accomplish that.
Thanks for any advice.
