REGRESSION 3.2-rcX: RTC auto poweron after 5 minutes

[Andreas Friedrich]

Hello,

I have found a RTC problem on my Toshiba Tecra notebook:

After shuting down my system (init 0), it powers on automatically
after 300 seconds!

I've detected this problem the first time with the stable kernel 3.1.5.
Bisecting leads me to the following patch:

"rtc: Disable the alarm in the hardware"
Stable 3.1.5:     0cbc008c56f7b4a11ba6fe80e196d7ab322baabf
Mainline 3.2-rcX: c0afabd3d553c521e003779c127143ffde55a16f

This change makes the newer kernels unusable for me. Maybe the Toshiba
BIOS does not work adequate, but my BIOS is already the newest version
and sorry, I can't fix the BIOS.

I've added some system info:
   dmesg.txt
   3.2-rcX.config
   lshw.txt
   lspci-vvv.txt
   proc_driver_rtc.txt
   proc_version.txt

With best regards,
Andreas Friedrich
