Description David Kovalsky 2010-05-24 10:08:17 EDT
Description of problem:
Xeon 3330, but it's not supported under current kernel/lm_sensors

syslog shows: 
kernel: w83627ehf: Found W83627DHG chip at 0x290  
kernel: coretemp: Unknown CPU model 17 

Version-Release number of selected component (if applicable):
kernel-2.6.18-194.el5
lm_sensors-2.10.7-9.el5

So I've tried the kmod-coretemp from elrepo with updated lmsensors from the
same repo:

http://elrepo.org/linux/elrepo/el5/x86_64/RPMS/kmod-coretemp-xen-1.1-6.el5.elrepo.x86_64.rpm

http://elrepo.org/linux/elrepo/el5/x86_64/RPMS/lm_sensors-2.10.8-2.el5.elrepo.x86_64.rpm


Works like charm. lm-sensors output:
coretemp-isa-0000
Adapter: ISA adapter
Core 0:      +38°C  (high =  +100°C)                   

coretemp-isa-0001
Adapter: ISA adapter
Core 1:      +25°C  (high =  +100°C)                   

coretemp-isa-0002
Adapter: ISA adapter
Core 2:      +34°C  (high =  +100°C)                   

coretemp-isa-0003
Adapter: ISA adapter
Core 3:      +41°C  (high =  +100°C)

Same problem here.
I had backported i5k_amb and coretemp kernel-modules as well as a backported lm_sensors-3 from Fedora 12 for Kernel 2.6.18-164 that worked without problems:

# sensors|grep Core
Core 7: +58.0°C (high = +74.0°C, crit = +100.0°C)
Core 6: +65.0°C (high = +74.0°C, crit = +100.0°C)
Core 5: +49.0°C (high = +74.0°C, crit = +100.0°C)
Core 4: +57.0°C (high = +74.0°C, crit = +100.0°C)
Core 3: +51.0°C (high = +74.0°C, crit = +100.0°C)
Core 2: +55.0°C (high = +74.0°C, crit = +100.0°C)
Core 1: +57.0°C (high = +74.0°C, crit = +100.0°C)
Core 0: +63.0°C (high = +74.0°C, crit = +100.0°C)

# sensors|grep DIMM
Ch. 0 DIMM 0: +61.0°C (low = +74.5°C, high = +124.0°C)
Ch. 1 DIMM 0: +57.0°C (low = +74.5°C, high = +124.0°C)

sensors-detect now works:

(...)
Intel Core family thermal sensor...                         Success!
    (driver `coretemp')
Intel AMB FB-DIMM thermal sensor...                         Success!
    (driver `to-be-written')
(...)
Driver `w83793' (should be inserted):
  Detects correctly:
  * Bus `SMBus I801 adapter at 1100'
    Busdriver `i2c-i801', I2C address 0x2f (and 0x4b 0x4f)
    Chip `Winbond W83793R/G' (confidence: 8)

Driver `coretemp' (should be inserted):
  Detects correctly:
  * Chip `Intel Core family thermal sensor' (confidence: 9)

Driver `to-be-written' (should be inserted):
  Detects correctly:
  * Chip `Intel AMB FB-DIMM thermal sensor' (confidence: 9)
(...)

At least coretemp should be loaded:

# tail -3 /etc/sysconfig/lm_sensors
MODULE_0=i2c-i801
MODULE_1=w83793
MODULE_2=coretemp

But fails:

# dmesg
coretemp: Unknown CPU model 17
coretemp: Unknown CPU model 17
coretemp: Unknown CPU model 17
coretemp: Unknown CPU model 17
coretemp: Unknown CPU model 17
coretemp: Unknown CPU model 17
coretemp: Unknown CPU model 17
coretemp: Unknown CPU model 17

i5k_amb is not present either

# lsmod|grep coretemp
# lsmod|grep i5k_amb

# find /lib/modules -name "i5k_amb.ko";find /lib/modules -name "coretemp.ko"

That is sad.
