Description Nicolas Mailhot 2007-12-02 10:59:51 UTC

Description of problem:

The main sensors device on my mobo is not working anymore. When I try to insert
the module manually I get

# /sbin/rmmod it87
ERROR: Module it87 does not exist in /proc/modules
# /sbin/modprobe it87
FATAL: Error inserting it87
(/lib/modules/2.6.24-0.62.rc3.git5.fc9/kernel/drivers/hwmon/it87.ko): Device or
resource busy

it87 is one of the most common sensor module, a lot of people are going to be
affected

Version-Release number of selected component (if applicable):
# uname -a
Linux rousalka.dyndns.org 2.6.24-0.62.rc3.git5.fc9 #1 SMP Sat Dec 1 13:59:08 EST
2007 x86_64 x86_64 x86_64 GNU/Linux

How reproducible:

always

oops. sorry about that, brainfart.

Comment 3 Dave Jones 2008-04-02 00:32:54 UTC

is this still broken with the latest builds ?  Despite your assertion of this
being common, none of my test systems have it, so I can't test.

Comment 4 Nicolas Mailhot 2008-04-02 08:10:19 UTC

A workaround was merged upstream just before 2.6.24 release. It was one of the
last release regressions to be fixed.

I am on F12, 2.6.31.5-127.fc12.i686.PAE
Sounds like the same problem, different kernel:

# sensors-detect
# sensors-detect revision 1.1
# System: Micro-Star Inc. MS-6566E

This program will help you determine which kernel modules you need
to load to use lm_sensors most effectively. It is generally safe
and recommended to accept the default answers to all questions,
unless you know what you're doing.

Some south bridges, CPUs or memory controllers contain embedded sensors.
Do you want to scan for them? This is totally safe. (YES/no): y
Silicon Integrated Systems SIS5595... No
VIA VT82C686 Integrated Sensors... No
VIA VT8231 Integrated Sensors... No
AMD K8 thermal sensors... No
AMD Family 11h thermal sensors... No
Intel Core family thermal sensor... No
Intel AMB FB-DIMM thermal sensor... No
VIA C7 thermal and voltage sensors... No

Some Super I/O chips contain embedded sensors. We have to write to
standard I/O ports to probe them. This is usually safe.
Do you want to scan for Super I/O sensors? (YES/no): y
Probing for Super-I/O at 0x2e/0x2f
Trying family `National Semiconductor'... No
Trying family `SMSC'... No
Trying family `VIA/Winbond/Nuvoton/Fintek'... Yes
Found `Winbond W83627HF/F/HG/G Super IO Sensors' Success!
(address 0x290, driver `w83627hf')
Probing for Super-I/O at 0x4e/0x4f
Trying family `National Semiconductor'... No
Trying family `SMSC'... No
Trying family `VIA/Winbond/Nuvoton/Fintek'... No
Trying family `ITE'... No

Some systems (mainly servers) implement IPMI, a set of common interfaces
through which system health data may be retrieved, amongst other things.
We first try to get the information from SMBIOS. If we don't find it
there, we have to read from arbitrary I/O ports to probe for such
interfaces. This is normally safe. Do you want to scan for IPMI
interfaces? (YES/no): y
Probing for `IPMI BMC KCS' at 0xca0... No
Probing for `IPMI BMC SMIC' at 0xca8... No

Some hardware monitoring chips are accessible through the ISA I/O ports.
We have to write to arbitrary I/O ports to probe them. This is usually
safe though. Yes, you do have ISA I/O ports even if you do not have any
ISA slots! Do you want to scan the ISA I/O ports? (yes/NO): y
Probing for `National Semiconductor LM78' at 0x290... No
Probing for `National Semiconductor LM79' at 0x290... No
Probing for `Winbond W83781D' at 0x290... No
Probing for `Winbond W83782D' at 0x290... No

Lastly, we can probe the I2C/SMBus adapters for connected hardware
monitoring devices. This is the most risky part, and while it works
reasonably well on most systems, it has been reported to cause trouble
on some systems.
Do you want to probe the I2C/SMBus adapters now? (YES/no): y

Now follows a summary of the probes I have just done.
Just press ENTER to continue:

Driver `w83627hf':
* ISA bus, address 0x290
Chip `Winbond W83627HF/F/HG/G Super IO Sensors' (confidence: 9)

Do you want to overwrite /etc/sysconfig/lm_sensors? (YES/no): y
Starting lm_sensors: loading module w83627hf No sensors found!
Make sure you loaded all the kernel drivers you need.
Try sensors-detect to find out which these are.

Unloading i2c-dev... OK
