NCT6686D-L #85

Loading the driver on a Lenovo P330 board, which uses a NCT6686D-L, results in an error:

[ 1003.123226] nct6687: Found NCT6686D or compatible chip at 0x002e:0x0a20
[ 1004.147175] nct6687: EC Invalid address: 0xFFFF

depending on the options (modprobe nct6687 force=1 manual=1) also

Update

I actually managed to get it working by adding acpi_enforce_resources=lax as a kernel parameter. The driver loads with modprobe after booting, yet it doesn't load while booting. During boot it shows:

Jan 18 18:16:04 qnx kernel: nct6687: loading out-of-tree module taints kernel.
Jan 18 18:16:04 qnx kernel: nct6687: module verification failed: signature and/or required key missing - tainting kernel

Jan 18 18:16:05 qnx systemd-modules-load[339]: Failed to insert module 'nct6687': No such device

While loading it with modprobe afterwards works and prints:

Update II I actually solved the loading during boot issue by adding: softdep nct6687 pre: i2c_i801 to a /etc/modprobe.d/ entry.

@Fred78290 would you like me to make a PR to update the doc regarding my two issues?
