[ 89.499095662,3] DT: dt_attach_root failed, duplicate sensor@9 In the msglog seeing the above error.

from 'ipmitool sdr elist -v' Sensor ID : OCC Active 2 (0x9) OCC Active2 Sensor is having sensor id 0x09

and also from p8dtu.xml having sensor id 0x09 assigned to boot-count-sensor and the same is not existing in the 'ipmitool sensor list'

<id>/sys-0/boot_count_sensor</id>
<property>
<id>IPMI_SENSOR_ID</id>
<value>0x09</value>
</property>

Firmware added only 'OCC Active2 sensor' not the 'boot count sensor' due to the duplicate sensor id.

/ # ipmitool sensor list | grep -i occ OCC Active 1 | 0x2 | discrete | 0x0200| na | na | na | na | na | na OCC Active 2 | 0x2 | discrete | 0x0200| na | na | na | na | na | na

/ # ipmitool sensor list | grep -i boot / #

• Severity of this bug, because of a duplicate id, some of the feature(s) are not getting enabled. In this case - 'OCC' got active and 'boot count sensor' was not.
