Hi,
I have supermicro x8sil-f (latest bios/ipmi fw) with 2 fans and it has started
to beep after a while when OS is up while it detected non-existing fans either
run at 0 RPM or in -2560 RPM.
OpenBSD itself used to detect both fans (though lm1.fanX numbers were different
to numbering from motherboard vendor).
I replugged both fans on the board and OpenBSD has detected only one fan now.
Why only one now, if it used to previously detected both?
# sysctl hw.sensors.lm1 | grep fan ; ipmitool -I lanplus -H 192.168.1.250 -U
ADMIN -P **** sensor list | grep '^FAN [1-2]'
hw.sensors.lm1.fan1=1028 RPM
FAN 1 | 955.000 | RPM | ok | 215.000 | 400.000 |
585.000 | 29260.000 | 29815.000 | 30370.000
FAN 2 | 1325.000 | RPM | ok | 215.000 | 400.000 |
585.000 | 29260.000 | 29815.000 | 30370.000
Could it be possible that openbsd lm driver messes something on the board
and makes the board think a non-existing fan runs -2560 RPM or 0 RPM?
After fans replug and OpenBSD detected only one fan, the board hasn't
started to beep yet. I don't get it...

Thank you for a tip or workaround.
