Thanks; merging.

There have been some rtc changes upstream:

- v3.2-rc5~43^2~4 (rtc: Disable the alarm in the hardware,
2011-11-22), cherry-picked as v3.1.5~23

- v3.2-rc7~23^2~2 (rtc: Expire alarms after the time is set,
2011-12-09)

but neither seems relevant.

My advice:

- Please test version 3.1.5 or newer from sid, testing, or
experimental.
- If that reproduces the problem, please also try 3.2-rc7 or newer
from experimental.
- If that reproduces the problem, please send a summary of the
problem to rtc-linux@googlegroups.com, cc-ing
linux-kernel@vger.kernel.org, Alessandro Zummo
<a.zummo@towertech.it>, John Stultz <john.stultz@linaro.org>, and
either me or this bug log so we can track it. Be sure to include
a link to <http://bugs.debian.org/646429> for the diagnosis and
be ready to answer questions if the developers have any.
- If you find yourself wanting to test a patch, see [1] for
instructions and feel free to do the actual building on some beefy
machine other than the one you're testing on.

Thanks much, and good luck,
Jonathan

Default Bug#653331: CPU#0 stuck for 23s, system does not boot

I was able to reproduce this in a VM after hacking the rtc-cmos driver
to return invalid alarm values. The patch I just sent out certainly
fixed the problem in that VM.

Design a system any fool can use, and only a fool will want to use it.

Thanks. I have tested 3.2-rc7 from experimental. Here's the log, not very exciting, it looks the same to me:
