Hi again. A first test on 13.1 is not working. Which is strange, this should be a NOP there, if I understand correctly.
It's going to a black screen in the VM when starting Xorg.
I need more time to test on head and verify my findings.
I'm having a problem properly testing this.
I'm stumbling on other issues.
On 13.1 the module loads ands seems to work though. What is broken there for me at present, using the head of the ports repo is the virtualbox X11 driver.
On head (installed from FreeBSD-14.0-CURRENT-amd64-20220812-6a70a0c8bfa-257314-disc1.iso) I get a kernel panic due to a giant locking issue, both with and without your patch.
I'm trying to understand what is going on. More help would be appreciated, since I have no idea what could be causing these two issues.
