[Bug 210751] "Could not resolve symbol [^^^GFX0.AFN2]" errors on Lenovo Ideapad 330s
https://bugzilla.kernel.org/show_bug.cgi?id=210751 Zhang Rui (rui.zh...@intel.com) changed: What|Removed |Added Status|REOPENED|RESOLVED Resolution|--- |DOCUMENTED --- Comment #7 from Zhang Rui (rui.zh...@intel.com) --- The EC event indeed happens around every second. To me, the handling for the EC event (0xC9) is broken as it references the AFN2 method which does not exist at all. And this results in the EC event not handled properly and it keeps on firing. As I mentioned earlier, this is a BIOS issue. For some of the ACPI BIOS bugs, we can workaround them in Linux kernel, but for issues like this, we can do nothing in kernel because we don't know what is missing in the BIOS and it can only get fixed in ACPI BIOS code by the OEM Vendor. So I will close this bug report, sorry that we can not help on this issue. You can check if there is any new BIOS release or not. -- You may reply to this email to add a comment.

https://bugzilla.kernel.org/show_bug.cgi?id=210751 --- Comment #4 from Zhang Rui (rui.zh...@intel.com) --- I close this because we don't observe any functionality issue so far. And the error messages are caused by buggy BIOS code we can not fix. I can propose a customized DSDT and you can rebuild your kernel with the customized DSDT, and you will not see these errors. Another potential issue is that why it fires every second. please try following command and attach the int-before and int-after log files. grep . /sys/firmware/acpi/interrupts/* > int-before; sleep 10; grep . /sys/firmware/acpi/interrupts/* > int-after -- You may reply to this email to add a comment.
