Hello,

yes, I did not have the sensors command installed.

I removed SPD5118 from the blacklist and I rebooted the system. This is what the
"sensors" command is reporting after the boot:

spd5118-i2c-1-50
Adapter: SMBus I801 adapter at efa0

I then tried to hibernate. Hibernation failed and the output of the "sensors"
command did not change.

I also tried to rmmod spd5118 and modprobe it. The output of the sensors
command does not show spd5118 anymore.

Hope I did what you asked properly.
Thanks for your answer.
