https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=203820 --- Comment #2 from martin ilavsky <ilavsky.martin@gmail.com> --- I neglected to mention this machine is using VirtualBox; it hosts several VMs (here all VMs are VirtualBox's VMs). I did following tests: 0) fresh boot without any VirtualBox kernel modules 1) fresh boot with VirtualBox modules loaded but no VM running 2) same as 1) but with at least one VM running During kldunload kernel crashed only when VM was running. Any other time unload was successful. Also if I started the VM, suspended it and then removed the vmm everything was ok. Crash occurs in the same function (step) as mentioned above. I was able to reproduce it every time when VM was running. -- You are receiving this mail because: You are the assignee for the bug.
