Nice.

This means amd_e400_idle is buggy, I guess.

I don't see any obvious fixes upstream, but since it's been a while,
it would be useful to check a more current kernel.  Please test a
3.1.y kernel from unstable, and if it reproduces the problem, send a
summary of your findings to linux-kernel@vger.kernel.org, cc-ing
Borislav Petkov <borislav.petkov@amd.com>, Boris Ostrovsky
<ostr@amd64.org>, x86@kernel.org, and either me or this bug log so we
can track it.

Be sure to mention:

 - reliable steps to reproduce the problem
 - which kernels you have tested and found to exhibit the problem
 - the newest kernel, if any, that worked fine
 - what happens when you boot with idle=mwait
 - full "dmesg" output from booting an affected kernel and reproducing
   the problem (as an attachment)
 - any other weird observations
 - http://bugs.debian.org/617635 in case someone reading wants the
   full story

Thanks and sorry we let this sit for so long.

Regards,
Jonathan
