JSI Tip 10063. When your Windows 2000 computer attempts to use a hardware device, you receive a STOP 0x000000DB, or STOP 0x0000007F, or STOP 0x0000000A?

When Windows 2000 attempts to use a hardware device that requires resources used by other devices, you receive one of the following:

Error message
STOP 0x000000DB (0x00000000, 0x000000FF, 0x00000000, 0x8046D604)
DRIVER_CORRUPTED_SYSPTES


Error message
STOP 0x0000007F (0x0000000D, 0x00000000, 0x00000000, 0x00000000)
UNEXPECTED_KERNEL_MODE_TRAP


Error message
STOP 0x0000000A (0x1b8f610a, 0x00000002, 0x00000001, 0x8046d9c4)
IRQL_NOT_LESS_OR_EQUAL

When a device sends a hardware interrupt (process request) for shared resources, Windows 2000 sets a flag in the IDT ( Interrupt Descriptor Table) to temporarily disable hardware interrupts, so that no other process can divert the resources. These STOP errors will occur if a hardware interrupt occurs between the time that Windows 2000 sends the request to disable hardware interrupts and hardware interrupts are actually disabled, because the IDT becomes corrupted.
