~ > lsmod | grep acpi_call
acpi_call 16384 0
For example,
~ > echo '\_SB.PCI0.LPC0.EC0.VPC0.DYTC 0x000FB001' | sudo tee /proc/acpi/call
\_SB.PCI0.LPC0.EC0.VPC0.DYTC 0x000FB001
gives me the following dmesg line:
[ 1254.833201] acpi_call: Cannot get handle: Error: AE_NOT_FOUND
Here is my journalctl output.
I'd guess the problem is caused by the errors from journalctl lines #371-#380, but I don't know how to proceed.
Any help? Thanks!
