Well, send me the output of grep . /sys/bus/platform/devices/thinkpad_acpi/hotkey* (and don't worry if it causes the kernel to complain loudly about access to deprecated attributes). I think the "ThinkPad" key works in CMOS NVRAM polling mode on your thinkpad, which means there is a higher chance that it is a driver bug. > A simple echo mem > /sys/power/state does the job, so it's not some > side effect of some other things being done by my regular suspend > script.

What happens when you unload and re-load thinkpad-acpi (rmmod and modprobe)? Does the key stop working? > Any hints as to how to debug or even fix this would be appreciated. If the rmmod+modprobe breaks it, it is a sure sign that the hotkey polling code in thinkpad-acpi is buggy (which is good, since it is something we can fix). -- "One disk to rule them all, One disk to find them.
