Attached is a one-liner patch for VBoxGuest.sys for Windows guest additions.
As mentioned in the ticket, the handler for IRP_MJ_POWER may be called at DISPATCH_LEVEL at shutdown unless DO_POWER_PAGABLE is set in the device object. The attached patch does just that. Another solution is to simply make the routine nonpaged. I have tested this patch on Windows 7 x86 CHK (where the defect originally reproduced) and it works here - additional testing priori to release may be desired to confirm no unexpected side-effects. -Dennis Lawler
