Created attachment 157972 [details] Screenshot of error VBoxDrvFreeBSDModuleEvent causes kernel panic on boot stable/10 - r281836 virtualbox-ose-kmod-4.3.28 This kernel panic isn't producing a crash core file. I can work around this temporarily by disabling `vboxdrv_load="YES"` inside /boot/loader.conf What can I do to give better debug info?
have you tried to rebuild kmod from ports? I remember the "same" error..
Can someone change the version this to 10-stable?
I also get this on FreeBSD 9.3 with virbualbox-ose 4.3.34 (after upgrading from 4.3.24). In my case the kernel modules seem to be loading fine (vboxdrv.ko, vboxnetflt.ko and vboxnetadp.ko). So with vboxnet_enable="YES" the system boots properly. The kernel panic is caused when I add the vboxheadless_enable="YES" to rc.conf. Or if I try to start the VMs manually after booting. So it seems that the panic is caused when the VMs are starting. In the kernel panic output I also saw the "spinlock held too long" message.
VBox version is at 5.2.4. 9.3 and 10.2 are gone. This is overcome by events.
