Win7 Vm does not start under Vbox 4.04. Crash does not release memory

[Francis Turner]

I have a 32 bit win 7 guest that will not start under VirtualBox 4.04 PUEL. It crashes after displaying the initial boot screen but before the animated windows logo would appear. I did install the USB extensions before attempting to start the VM. On a subsequent start windows offers to try and rebuild things but that too crashes at about the same place.

Furthermore once crashed, window commands to reset/ACPI Shutdown or close (i.e. HOST R etc.) do not work. They simply cause the window to fail to respond to further commands. It is possible subsequently to use the host linux window manager (XFCE) to force the closing of the window. However no matter what command is issued, while the VBox GUI claims the VM 'aborted', memory is not released even though a list of processes does not display the VM and the window has been closed by the host window manager.

This VM does start correctly up with VB 3.2.12 r68302.

A Windows XP VM and a Ubuntu VM do both start up correctly with 4.04

The host OS is 32 bit Xubuntu 10.04 (Linux 2.6.32-28-generic-pae #55-Ubuntu SMP Mon Jan 10 22:34:08 UTC 2011 i686 GNU/Linux )

Here are the Vm details while running in 3.2.12 which I have now downgraded back to
