dmesg from 4.12.4
This is just a warning that your BIOS has misconfigured the pin. It has direct_irq flag set which means it is supposed to trigger interrupts toward IO-APIC when the line is active. For some reason the BIOS seems to want to use the same pin as output as well which does not work well. Can you attach acpidump of the machine to the bug? Created attachment 257847 [details]
acpidump from lenovo 100S 11IBY, latest dated bios
OK, thanks. So it is one of the i2c-hid devices that controls power in _PSx methods using a GPIO that is misconfigured. While the kernel warns about it, it still re-configures the pin so things should work. This is BIOS issue which should be fixed there. I believe this is something which Hans (Cc'ed now) has fixed a couple of years ago. (In reply to Andy Shevchenko from comment #9) > I believe this is something which Hans (Cc'ed now) has fixed a couple of > years ago. Correct, this if fixed by: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=e2b74419e5cc7cfc58f3e785849f73f8fa0af5b3 So lets close this bug. |
