Re: [lm-sensors] Supermicro X7SPA-HF: in4 ALARM

[Ben Kamen <bkamen@benjammin.net>]

Hey guys, in response to this email below from Jean,

  Can we still use lm_sensors on the winbond IC on the board or should lm_sensors be disabled entirely?

I'm also using an X7SPA-HF and the thermal management goes wonky after a few hours of normal operation.

(temp alarm, fans report erroneous speeds and so forth)

When this started happening, I began to wonder about contention between the IPMI controller onboard and what linux might be trying to do at the same time.

Thanks,

  -Ben
