Subject: windfarm_fcu_controls: cpu-pump-0 <HW FAULT>
Date: Fri, 02 Aug 2013 21:08:25 +0200 [thread overview]
Message-ID: <87r4eb52s6.fsf@igel.home> (raw)
wf_fcu_fan_get_rpm is returning EFAULT when reading the values for the
cpu pump controls on the PowerMac7,3. Also, wf_fcu_get_pump_minmax is
unable to get the real limits and falls back to using the defaults.
Here is the output when DEBUG is defined:
wf_fcu: FCU Initialized, RPM fan shift is 3
