Hi,
I've installed lm_sensors and i2c on my Via Epia ME6000 with Red Hat 9.
When i run sensors-detect it ends with a segmentation fault after which
only a reboot helps to kill the processes
Below i've posted what appears on the console, dmseg and lsmod.
Hope you can help. Thanks.
------------- on console ------
BIOS vendor (ACPI): VT9174
System vendor (DMI): VIA Technologies, Inc.
BIOS version (DMI): 6.00 PG
We can start with probing for (PCI) I2C or SMBus adapters.
You do not need any special privileges for this.
Do you want to probe now? (YES/no):
Probing for PCI bus adapters...
Use driver `i2c-viapro' for device 00:11.0: VIA Technologies VT8233A/8235
South Bridge
Probe succesfully concluded.
We will now try to load each adapter module in turn.
Load `i2c-viapro' (say NO if built into your kernel)? (YES/no):
Module loaded succesfully.
Do you now want to be prompted for non-detectable adapters? (yes/NO):
To continue, we need module `i2c-dev' to be loaded.
If it is built-in into your kernel, you can safely skip this.
i2c-dev is not loaded. Do you want to load it now? (YES/no):
Module loaded succesfully.
We are now going to do the adapter probings. Some adapters may hang
halfway
through; we can't really help that. Also, some chips will be double
detected;
we choose the one with the highest confidence value in that case.
If you found that the adapter hung after probing a certain address, you
can
specify that address to remain unprobed. That often
includes address 0x69 (clock chip).
Segmentation fault
