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
