[REGRESSION] 41c7f74 rtc: Disable the alarm in the hardware (v2)
From: Brecht Machiels
Date: Sun Dec 01 2013 - 16:10:21 EST
Hi,
I recently installed (Arch x86_64) Linux with the 3.12.1 kernel on a Toshiba Satellite L300 laptop. After shutting down Linux, the laptop will spontaneously boot up after about five minutes. This seems to be consistent. There are no options in the BIOS for en/disabling or configuring the RTC wakeup alarm. After 'shudown --halt' and shutting down the laptop manually (pressing the power button for 3 seconds), it will not spontaneously boot up. I understand Linux is configuring the RTC alarm on shutdown?
After finding some other reports of similar problems, I have built a custom 3.12.1 kernel after reverting commit 41c7f74 (rtc: Disable the alarm in the hardware (v2)) [1]. This seems to solve the problem for me.

Both LKML threads seem to have died without any action being taken.
Setting the RTC alarm time way in the future, as suggested in [2] didn't work for me.
Output of dmidecode is attached. Please let me know if any other information could be useful.
