I had a closer look at the issue. I think what is happening is that you don't enter the do/while loop in cmos_resume twice. That is supposed to handle then clear the RTC_AIE bit and that is why the alarm still seems enabled.
Can you add some tracing there to understand why? It is probably also useful to know the value of cmos->suspend_ctrl in cmos_suspend.
My guess is that is_intr(mask) is false and you break out of the loop at the first pass, meaning that the RTC_AIE bit is never cleared from RTC_CONTROL. That would also mean that your RTC is not setting RTC_AF after waking your PC. Am I right?
