At a dedicated server (i3770) I'm realized today that the sensors # have been switched between 3.17.3 and .4.

With 4 I do have :

# tail -v /sys/devices/virtual/thermal/thermal_zone?/temp
==> /sys/devices/virtual/thermal/thermal_zone0/temp <==
64000

==> /sys/devices/virtual/thermal/thermal_zone1/temp <== 27800

==> /sys/devices/virtual/thermal/thermal_zone2/temp <== 29800

whereas with with 3.17.3 the highest temperature (about 60°) was shown at sensor 2.

Intended or a regression ?

Hhm,
booting now into the same hardened kernel version, but new revision-r1 (new grsec patch) reverts it again, now I do have:

# tail -v /sys/devices/virtual/thermal/thermal_zone?/temp
==> /sys/devices/virtual/thermal/thermal_zone0/temp <==
27800

==> /sys/devices/virtual/thermal/thermal_zone1/temp <== 29800

==> /sys/devices/virtual/thermal/thermal_zone2/temp <== 67000
