The RTM and Service Pack 1 versions of the latest Windows client can fail to play nice with restarting multicore-processor computers, according to Microsoft. Micrsoft described the problem as follows: “when you restart a multicore-processor computer that is running Windows Vista, you may receive the following Stop error message: “STOP 0x0000007B (parameter1, parameter2, parameter3, parameter4) INACCESSIBLE_BOOT_DEVICE.” This problem is more likely to occur on a virtual machine.”

“This issue occurs because of a race condition in which one thread reads some data that is being written by another thread. This race condition causes the PCI root node to be absent from the device tree. Therefore, the system generates a Stop error because the storage device that the system relies on is missing,” Microsoft explained.
