It seems something wrong with Slot 4, I switched the memory between Slot 4 and Slot 3, still have the same result, I guess something wrong with Slot 4, or mainboard problem...

Any suggestion for me ?
Thanks!

Yes - place a call with HP to investigate the hardware.

Hi,

Can u give me the model # of the machine and also the copy of /var/tombstones/ts99 file - I shall decode for you and analyze the root cause.

Here is the report

Looks like the problem with AMC Bus0 problem detected.

Report
------

PDC version has been found to be : 42.19
This HPMC appears to come from a Lclass system. No System Bus Adapter (IKE) has been found in the PIMDUMP
Because we have no IKE found, I will assume that this is a L1xx or L2xx.
Looks like this is a 2 CPUs system
All timestamps are valid and within each others ..
There is at least one chassis code different from 6322. Let s look at it
The CPU 1 has a chassis code different from 6322.
The second chassis code is equal to 6302 : Runway Path error.
Most likely we have a DIMM problem on this system .
Estat in CPU status0 indicates a Master Path Error
Most likely the problem comes from a failing DIMM. Let's try to decode some additional chassis code to identify the DIMM.
We could not find a chassis code to decode directly the DIMM. Let's look at the other chassis codes .
Found one chassis code describing a bad DIMM .
The chassis extension is : 0x0000ff000004ff74
The failing DIMM is : Carrier 00 Slot 04
Found one chassis code describing a bad DIMM .
The chassis extension is : 0x0000ff000004ff74
The failing DIMM is : Carrier 00 Slot 04
The most suspect part in this HPMC is : DIMM0004DIMM0004

thanks Anand !
So, what can i do now ?
And what kind of tool did you use to generate such report ?

These results are decoded from wtec site- which is accessible only through HP network.

The next step is to replace the part.
