Your ACPI driver is loaded. The user attempts to read a value from a
thermal hwmon chip. You execute SBWB in order to write the register
address to the chip. You then take an ACPI interrupt. The ACPI core
executes a method that executes SBWB and writes a different register
address to the chip. Control passes back to you. You call SBRB and read
back a value from the wrong register.
