lm_sensors vs. IPMI

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



When I set the priority to zero in both i2c-ipmi.c and i2c-ipbm.c, those modules compile, install, and load fine.  But sensors-detect doesn't detect anything and manually loading adm1026 succeeds but shows no sensors.  Can you point me towards more documentation on how to use the i2c-ipm* modules or suggest what I should try next?

Thanks.
