Package: linux-source-4.9 Version: >=4.9.25 eeepc-wmi doesn't work with my Eee PC netbook (Asus X101) after kernel upgrade from 3.14.79 to 4.9.y. So some Eee WMI hotkeys don't work with the new kernel. kern.log: ------- [ 1.043620] eeepc_wmi: Found legacy ATKD device (ASUS010) [ 1.043632] eeepc_wmi: WMI device present, but legacy ATKD device is also present and enabled [ 1.043650] eeepc_wmi: You probably booted with acpi_osi="Linux" or acpi_osi="!Windows 2009" [ 1.043662] eeepc_wmi: Can't load eeepc-wmi, use default acpi_osi (preferred) or eeepc-laptop evtest output: Available devices: /dev/input/event0: Lid Switch /dev/input/event1: Sleep Button /dev/input/event2: Power Button /dev/input/event3: Power Button /dev/input/event4: Video Bus /dev/input/event5: AT Translated Set 2 keyboard /dev/input/event6: HDA Intel Headphone /dev/input/event7: SynPS/2 Synaptics TouchPad ------------ eeepc-laptop is not good for Asus X101. It works only with acpi_osi=Linux, but the KEY_BRIGHTNESSDOWN and KEY_BRIGHTNESSUP don't work in this case. I have to use eeepc-wmi. The patch "Use acpi_dev_found() " is the cause of the problem. /part of vanilla kernel/ https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git/log/drivers/platform/x86/eeepc-wmi.c?h=v4.9.51 ... I removed this patch from my kernel source, and eeepc_wmi works correct.: kern.log: [ 1.048511] input: Eee PC WMI hotkeys as /devices/platform/eeepc- wmi/input/input5 evtest output: Available devices: /dev/input/event0: Lid Switch /dev/input/event1: Sleep Button /dev/input/event2: Power Button /dev/input/event3: Power Button /dev/input/event4: Video Bus /dev/input/event5: Eee PC WMI hotkeys /dev/input/event6: AT Translated Set 2 keyboard /dev/input/event7: HDA Intel Headphone /dev/input/event8: SynPS/2 Synaptics TouchPad I suggest to remove the bad patch /for example with attachment/ from the kernel source .

It doesn't appear to make any functional change. Are you still putting an acpi_osi parameter on the kernel command line? Ben. -- Ben Hutchings Make three consecutive correct guesses and you will be considered an expert.

Dear Ben Hutchings,
Dear kernel developers,
First I want to thank you all for your amazing work.
It moves me to see how you all work on this humongous project so successfully and coordinatedly.
I am not a kernel developer and I watch in awe how you accomplish all this.
Nonetheless, I plead for rolling back to the old test
if (eeepc_wmi_check_atkd()) {...}
in eeepc_wmi_probe() that was in effect until kernel 4.6.7
rather than the new test
if (acpi_dev_found(EEEPC_ACPI_HID)) {
used as of kernel 4.7.x
because the new test prevents loading eeepc-wmi
while the old one loads it,
just as Oscon has described.
I own seven boxes Eee PC 1001PXD
https://www.asus.com/Laptops/Eee_PC_1001PXD/
and want to prepare them with Debian 9 and give them to people for free
who cannot or do not want to afford to buy a new laptop.
Also I want to encourage improving the current drivers for Asus EeePCs.
In order to support your work, I offer to send one or two of my boxes
for testing purposes to kernel and driver developers.
And, of course, I am willing to desribe all the relevant bugs
that I have encountered on these boxes in sufficient detail whenever required.
Please let me know how else I can support.
And, of course, I will pay the postage.
Cheers, and again thank you for your awesome work!
Roland
