I don't think this has anything to do with amount of memory.
Just glancing at the assert, I think that the vbox video driver that got installed was for made for win2008, in which MmFreeContiguousMemory can be called at IRQL<=DISPATCH_LEVEL. In reactos we Are using PAGED_CODE, which causes the assert. We should remove it as we are shooting for win2008.

Is it official build or your own? Could you regress-test it to precise revision when it got broken?

steps to reproduce are:


1.- Install VBox guest additions
2.- Change color depth to 32-bit
3.- reboot
4.- Once rebooted in 32-bit color depth mode, shutdown ReactOS

ReactOS will crash
