Bug#876303: [Fwd: Re: Re: Bug#876303: linux-source-4.9 kernel regression eeepc-wmi]
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
