Spurious power button event on resume from hibernate

[Francis Russell <francis+lkml@unchartedbackwaters.co.uk>]

Hi all,

I have a Samsung R560 laptop running amd64 Debian testing with a
2.6.29.3 kernel compiled from vanilla sources. Upon resume from
hibernate, it appears that the OS receives a power button event that
causes the system to shut down. I've verified this the best I can by
killing acpid then watching the output of /proc/acpi/event during
hibernate (triggered by writing 'disk' to /sys/power/state).

This problem looked very similar to that discussed in another Bugzilla
entry (http://bugzilla.kernel.org/show_bug.cgi?id=6612) so I had I
extended the changes made by the patch in the obvious way to the S4
state but it made no difference. Is this something the kernel should be
handling? How can I debug this further?

Many thanks,

Francis
