To fully understand what's going on, let’s take a deeper look at how ACPI in the BIOS (ACPI BIOS) and in the operating system (ACPI OS) talk to each other in situations that might give rise to this error.
I'll provide some technical background on the problem, and then I'll look at a few remedies.
The Advanced Configuration and Power Interface (ACPI) is a part of the BIOS and the operating system.
This machine has suffered a fatal error and needs to be shutdown as quickly as possible.
They may also receive a variation of this error in the event log, referring to ports other than 0x70-0x71. The variances between ACPI in the BIOS and in the operating system can cause different outcomes in different systems when simultaneous I/O read/write operations are attempted.
This is because different motherboards run different chipsets, which in turn run different BIOSs, and it’s up to the manufacturer to decide when to release a given update.
