i have a idea what one cause could ne

+                nfval =
+                    ath9k_hw_get_nf_limits(ah, chan)->cal[i];
+                if (nfval > -60 || nfval < -127)
+                    nfval = default_nf;

This is just a check to make sure we have sane calibrated values. Anything above -60 or under -127 will not work so
we take nominal value.

yes. but that means all < -127 and all > -60 catches it. this is the full value range. the check is wrong
everything is above -60 and bellow -127 at the same time. OR must ne AND

Not really. Note the negative numbers.
-60 is a bigger value than -127.
The expressions states that all values from -127 to -60 are valid.
