SYMPTOMS
When you start your Microsoft Windows XP-based computer you may receive the following Stop error message after the Windows XP splash screen appears:

Stop 0x000000D1 (0x0000001c, 0x00000002, 0x00000000, 0xf75ba58e)

DRIVER_IRQL_NOT_LESS_OR_EQUAL (d1)

An attempt was made to access a pageable (or completely invalid) address at an interrupt request level (IRQL) that is too high. This is usually caused by drivers using improper addresses.



CAUSE
This problem occurs because of a race condition that occurs in the ACPI power management code. The race condition occurs when the BIOS for the computer contains multiple tables and at least two of the tables contain power resources. This causes the ACPI code to access nodes that are not initialized, which creates the race condition.
