ACPI uses acpi_get_register() in order to get into suspend. This function is guarded by acpi_gbl_hardware_lock, which will be carried into resume phase. At resume interrupts are enabled and first ACPI interrupt deadlocks on this lock. Solution seems to be to not lock register read, as there are no concurrent activity at this point.
