5263	Host crash with 64-bit Guest on 32-bit SLED10 SP2 on Intel Core 2 Duo	Anders Olsson		"When upgrading from Novel SLED10 SP1 to SP2, VirtualBox has stopped working on all our Intel Core 2 Duo Machines. There is no problem with upgraded AMD Opteron Machines.

We've replicated this with VirtualBox OSE 2.1.4 and 3.0.8 as well as VirtualBox PUEL 3.0.8. The hardware we've tested with is HP xw4400 (BIOS 2.06) and Dell Inspirion D630 (BIOS A16).

The symptoms are that the guest booting halts after the GRUB menu. Either one waits for a few minutes or close the VM, both result in the host machine hanging. The screen remains static, and the only successful action is holding down the power button.

For testing, I've compiled and installed the vboxdrv module with BUILD_TYPE=debug. I've left the vboxnetflt and vboxnetadp out.

I've attached the vboxdrv logs in /var/log/messages and the vbox.log from a whole session started right after the module loaded. That session was left running until the machine crashed.

The Virtual Machine's configuration:
HW Virtualization: on
Host type: OpenSuSE (64bit)
Memory: 512MB
Nested Paging: off
IO APIC: on
ACPI: on
PAE: off
CPUs: 1
NICs: 3 Internal FastIII
3D Acc: off
Primary IDE Master: 1 30GB VDI
COM1: Enabled, Disconnected

Guest OS: SLES10 SP2 64-bit
Ubuntu 9.04 64-bit has also been tested, with similar, but not identical result. It manages to boot all the way from the CD, but the host still crashes when the VM is shut down."	defect	closed	VMM/HWACCM	VirtualBox 3.0.8	fixed	VT-x SLED10		Linux	Linux
