I think it is related to last diff commited:
----------------------------
revision 1.50
date: 2016/04/26 09:42:57; author: semarie; state: Exp; lines: +6 -3;
commitid: ZEmGqTk6vXPvhhU5;
corrects acpitz problem with active cooling and hysterisis
"if the temperature is below the active cooling level for a tz, turn the fan off
regardless of what state it is currently in"
ok mlarkin@
----------------------------
the error message should coming from acpitz_setfan() function.
I will try to understand elements.
Could you try the following diff (reverting previous commit) in order to

Do you see any acpitz0 message again (perhaps just one) ?
Thanks.
