Description jordan hargrave 2006-11-06 19:02:30 EST
Description of problem:
ipmitool reports incorrect readings on Woodcrest CPUs

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Install RHEL5 on system with Woodcrest CPUs
2. run ipmitool sdr list
Actual results:
temperature sensors for CPU report negative values

Expected results:
Sensors should not be displayed

Additional info:
The Woodcrest CPUs no longer have ambient temperature sensor information
The IPMI sensors have the sensor scanning disabled bit set; ipmitool ignores
this if there is a reading value returned.  This reading should always be
ignored if sensor scanning bit is enabled

Can somebody from RH please change the Version field to "5.0.0" from "rhel5-rc1"
as I do not have the permissions to do so.

Important Dell ipmitool fix needs to be in RHEL4.0. Adding ACK flags.

Issue is fixed with test packages provided in comment #10.
Comment 12 John Feeney 2006-12-14 16:12:26 EST
Even though this has a MODIFIED status, Dell wants to make sure that this is
shipped in 5.0.0 and is fixed their systems. Thus Dell wants it to be a blocker
for 5.0.0.
Comment 14 Amit Bhutani 2006-12-20 06:16:46 EST
OpenIPMI-2.0.6-5.el5.2 is now in RC Snapshot 3, so this can safely be marked as
VERIFIED. RH- Please close.
