Michael,
I have one-line workaround for this issue.
Could you try it?
However, seems additional thinking is required on hpifan interface.
The problem is:
- Manual Mode for HPI fan control mappped to System Manager controlled
cooling.
- Auto Mode for HPI fan control mappped to Shelf Manager controlled cooling.
- Default startup mode for Fan control is auto mode.
- hpifan calls saHpiControlGet( mode, state ) and then saHpiControlSet(
mode, new_state ).
- HPI spec says: If the CtrlMode parameter is set to SAHPI_CTRL_MODE_AUTO,
then the CtrlState parameter is not evaluated.
The workaround changes hpifan to always set manual mode.
And it is not clear now how to return to auto mode.
