Description Neel Chauhan freebsd_committer freebsd_triage 2020-07-29 04:38:19 UTC 
When I use VirtualBox on 13-CURRENT r363508, and attempt to use a bridged network, I get a kernel panic. This issue doesn't exist on 12.x.

System:
HP Spectre x360 13-ap0053dx
Intel Core i7-8565U
16GB DDR4
512GB NVMe + Intel Optane
13" 4K Touchscreen
Intel AC-9560 (iwm)

Patch

VirtualBox does not use EPOCH on 13, so this patch adds support for EPOCH in VirtualBox.

well, didn't read your comment, sorry.
Comment 8 Kubilay Kocak freebsd_committer freebsd_triage 2020-07-29 05:07:06 UTC 
Bug 244819 is a report of a freeze, not panic, not technically a duplicate. Are the freeze symptoms still reproducible, or is it *now* a crash?
Comment 9 Neel Chauhan freebsd_committer freebsd_triage 2020-07-29 05:17:41 UTC 
It technically is a panic, it just appears as a freeze with Nvidia graphics which my desktop use (the prior ProDesk mentioned and my current HP Omen).

I called a freeze since I didn't investigate further. I now know it is a panic.

BTW the patch is for emulators/virtualbox-ose-kmod.

Patch (Revision 2)

The patch should go into emulators/virtualbox-ose, as emulators/virtualbox-ose-kmod picks up the former's files.

This is a full patch.

I confirm this working, even on the previously "freezing" computers (Nvidia graphics) and the panic computers (Intel graphics).

… reading this alongside emulators/virtualbox-ose-kmod kernel panic bug 249326

This was fixed in r560502 (yay, Ports commit bit!).
