Comment 26 for bug 267682

Some further data. slangasek and I got together downtown to look at his keyboard issue, which is the same thinkpad model as mdz's. His particular symptoms are that the sleep key works one time, and then not after that. Looking into this, we found that at the kernel level, it prints the correct keycode once to /proc/acpi/event, and then nothing after that. Unloading the thinkpad-acpi kernel module and re-modprobing it causes the behavior to reset, with the key printed one time again. The /etc/acpi/sleepbtn.sh script does get called, but the machine does not sleep.

So at this point, I think we're seeing at least two different unrelated bugs - one is this thinkpad-acpi issue (which slangasek and I think is a kernel bug, and I'll file a task against it). I also think this is a Thinkpad-specific kernel bug.

Pitti and I (on Dells) are not seeing this particular bug, but are seeing something different, where the keys are showing up as mapped, but the functionality (sleep, battery, etc.) are not getting triggered. I do not find evidence that /etc/acpi/sleepbtn.sh is getting called.

I'm certain there are also additional bugs beyond this in the acpi/power-management handling code that we're running into. I think we should probably limit the scope of this bug report to the thinkpad-acpi issue. I'll file the dell sleep issue as a new bug.
