VBoxHeadless dumps core on 5.0.12 under fc22 - can't start Win8.1 guest

[iandekit]

I upgraded from 5.0.8 to 5.0.12 along with an OS dnf update... kernel went from kernel-4.2.3-200.fc22.x86_64 to kernel-4.2.8-200.fc22.x86_64

This is for VirtualBox-5.0-5.0.12_104815_fedora22-1.x86_64

After this my Win8.1 guest OS would not start; showed Aborted in phpvirtualbox window.

Inspection of the kernel logs shows lots of these:

Tried 'dnf reinstall VirtualBox-5.0-5.0.12_104815_fedora22-1.x86_64' ; no better.

Went back to 5.0.8 on same kernel; all fine.

This hardware is a Sun X2270M2.

I have the same VirtualBox 5.0.12 and kernel 4.2.8-200.fc22.x86_64 running on other hardware (eg: X4-2, X4100M2)but with different (linux) guest OS's and they seem fine.

The appropriate matching extpacks were installed.

backtrace, not munged by bug tracker editor

[Frank Mehnert]

The crash is related to HDA audio. Unfortunately you didn't attach the VBox.log file but I guess the initialization of the audio backend failed for some reason. The VBox.log file would tell this. Chose another audio backend or chose the NULL audio backend. And attach the VBox.log file of a crashed VM session.

I think this is a duplicate of #14960.
