Subject[regression] Re: [ 049/149] rtc: Disable the alarm in the hardware (v2)
Hi,

Sorry, I'm a little late. This seems to be causing spurious wakeups
after shutdown on some systems just like v1 did. :/

Janne Boman reports[1], using an HP EliteBook 8530w:

| somehow it restarts.

Based on a quick web search, Heinz Wiesinger, using the same model,
ran into the same problem and bisected it to this patch:

https://bugzilla.kernel.org/show_bug.cgi?id=44261

Janne confirmed the same by testing kernels closely based on 3.2.13
and 3.2.14 --- 3.2.13 shut down fine, while on 3.2.14 "shutdown -h
now" behaved roughly speaking like "reboot". A kernel close to 3.6.4
was also affected.

Known problem? An acpidump and kernel log can be found at [2].

Looking forward to your thoughts,
Jonathan
