Bug 224359

Hi,

I am collecting my servers temperature, fan speeds and sel logs with ipmitool. Yesterday, one of it get kernel panic, caused by ipmi.

Os: FreeBSD 11 Stable r320710
HW: DELL R730
Scripts:
/usr/local/bin/ipmitool sel list
/usr/local/bin/ipmitool sdr type "Power Supply"
/usr/local/bin/ipmitool sdr type "Fan"
/usr/local/bin/ipmitool sdr type Temperature
