Description Aurel Bodenmann-Flury 2018-11-26 18:22:21 UTC
I'm opening a new PR since I'm not sure, if my problem is related to https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=230460 or not (seems to me as if it isn't). I get an instant kernel panic when I start vboxwebsrv or a VM on a 12.0 PRERELEASE system:

/var/crash# uname -a
FreeBSD Server 12.0-PRERELEASE FreeBSD 12.0-PRERELEASE #2 r328635M: Fri Nov 23 14:32:30 UTC 2018     root@Server:/usr/obj/usr/src/amd64.amd64/sys/GENERIC  amd64

Virtualbox has been rebuilt:

/var/crash#  pkg info -f virtualbox-ose\* | egrep "^Name|^Installed"
Name           : virtualbox-ose
Installed on   : Sat Nov 24 10:05:11 2018 UTC
Name           : virtualbox-ose-kmod
Installed on   : Sat Nov 24 10:05:08 2018 UTC

r482464 (see https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=230460) is installed

/usr/ports/emulators/virtualbox-ose/files# ll patch-src-VBox-HostDrivers-VBoxNetFlt-freebsd-files_vboxnetflt
-rw-r--r--  1 root  wheel   638B Oct 20 04:42 patch-src-VBox-HostDrivers-VBoxNetFlt-freebsd-files_vboxnetflt

I even disabled SMAP

/var/crash# cat /boot/loader.conf | grep hw.cpu_stdext_disable

Still, the system crashes instantly:

/var/crash# less core.txt.3
Server dumped core - see /var/crash/vmcore.3

Duplicate of PR 233515?
Comment 2 rkoberman 2018-12-20 07:11:23 UTC
I am seeing the same issue. My stack trace is almost the same, but I do have two more frames on the stack.

#6  0xffffffff81077479 in trap_pfault
#7  0xffffffff81076a9e in trap
#8  <signal handler called>
#9  0xffffffff80c9863d in ifindex_alloc
#10 if_alloc (type=6 '\006')
#11 0xffffffff82a4502a in vboxNetAdpOsCreate
(Below this, it is the same.)

All of my ports were rebuilt on v12. I am at r342152 with a GENERIC config except SCHED_4BSD replacing SCHED_ULE. No issues seen prior to the upgrade.

I can make full dumps available.
