kernel regression from stable to testing (acpi lid / EEEpc 1215p)

Show all headers | View raw

Hi.


On my EEEpc 1215p laptop, the upgrade from stable to testing broke the 
lid switch detection, since
* another OS detects it just fine and acts on it;
* the kernel from stable (4.9.0-7) does too
Therefore, HW is ok (not obvious on an old laptop...)


If I use the current kernel in testing (4.19.0-1), or really any 
"testing" kernel from december onwards (when I upgraded), this is the 
situation:
* the sleep keycombo Fn+F1 works
* pm-suspend works
* pm-hibernate works
If I observe the state of /proc/acpi/button/lid/LID/state from a remote 
shell and close the lid, it shows "open". Indeed, the fact that I can 
still use the system is a dead giveaway it's not suspended :P

/etc/default/acpi-support is fine: LID_SLEEP=true is active, both acpid 
and the system itself were restarted multiple times.

Closest bug I could find witha similar issue is not relevant, since it's 
way older than my working kernel: 
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=820422


dmesg has this interesting warning:
ACPI: button: The lid device is not compliant to SW_LID.

Digging around, the common reply was along the lines of "meh, just a 
warning, ignore it if it works". Well, guess what, it doesn't :(


What's the best way to handle this? IMHO it's quite likely a kernel 
issue, most likely upstream.
Should I file a bug on linux-image-amd64 or directly on bugzilla.kernel.org?


Thanks,
Andrea.
