If anyone has any objections, please let me know. 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: | I'm unable to shutdown my system via normal means. The system | completes the shutdown process, all hardware lights are off, but then | 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 [1] http://bugs.debian.org/691902 [2] http://bugs.debian.org/cgi-bin/bugreport.cgi?msg=78;bug=691902
