| |
Hi Rafael / Len,
When i press the power-button on my intel NUC, i get twp ACPI power-events shortly after one another (within a second), instead of just one.
It doesn't matter if i have the old /proc/acpi interface enabled or disabled in the kernel config.
I have tested a few older kernels lingering around on the box and 3.14 already has this problem. 3.2 (from the debian repo) doesn't have the problem, it only fires one event.
I did find another report: Re: lenovo ultrabay docking station: if power button pressed 1x it creates 2x the same ACPI event http://www.spinics.net/lists/linux-acpi/msg54723.html But that hasn't come to a conclusion ...
Unfortunately 3.2 - 3.19-rc4 is a bit of a largish bisect window, so that's unfeasible :-)
I compiled in apci debug support and tried: echo "0x00080000" > /sys/module/acpi/parameters/debug_layer echo "0xffffffff" > /sys/module/acpi/parameters/debug_level
But i don't get any extra output in dmesg ?
Do you have any ideas for a debug patch or better values to figure out what is going on ?
