Re: [ros-dev] [ros-diffs] [cgutman] 46237: - Add a hack to disable ACPI if VMware is detected - This hack circumvents the main blocker that prevents enabling ACPI in trunk

[Olaf Siejka]

ACPI doesnt work with vbox guest additions, which is a trunk blocker as
well, IMO. Patch provided by aicom fixes the crash but introduces/leaves the
following random crash:
