Installation of VB 4.1.0 or 4.1.2 causes the system to freeze during the VB kernel module installation process. Nothing is logged in messages and nothing is displayed on the console. The system must be powered off, and then upon reboot it freezes again when the kernel modules are loaded on boot. If I boot the system in verbose mode, no errors are displayed. The only way I've found to recover is by booting from CD, mounting the hard drive, and uninstalling VB 4.1.x. I've tested & duplicated the problem with three clean Solaris Express installs on different hard drives in this system. VB 4.0.12 installs & functions normally & reliably. Since there are no logs, I am attaching as much system info as I can think of. I've also tried disabling various features of the BIOS including Vt-x & Vt-d. Details of the host hardware include: Dell OptiPlex 990, BIOS v. A05, Intel i7-2600 CPU, Intel Q67 chipset, 16GB DDR3 dual channel memory at 1333 MHz, Dual SATA3 1TB hard drives (recognized as SATA2) as zfs mirror, NVidia GeForce 210 video, Intel 82574L add-in PCIe ethernet card ",defect,closed,host support,VirtualBox 4.1.2,obsolete,,,other,Solaris
