IBM xSeries 346 _PCPU 3 didn't have heartbeat for 62 s. *may* be locked up

[credfern]

The server i am currently working on is an IBM xSeries 346. I previously had 3.0.2 installed on this machine and i recently tried upgrading to 3.5.

After the server boots, this is displayed in red font:

0:00:02::00.403 cpu2:1026)Heartbeat: 470: PCPU 3 didn't have a heardbeat for 62 seconds. may be locked up

0:00:02:00.403 cpu3: 1036)NMI : 1625: Faulting eip :esp

I used the UpgradeXpress CD to upgrade the BIOS and BMC hoping it would fix the problem but it did NOT.

Any ideas?

Hello,

Have you checked back farther in time to see if it was present before the upgrade.

I have encountered related errors on the 346/345 which where actually mismached CPU's from the factory.

Or you could have a mobo problem.

This was not present before the upgrade. And I am having this problem with both a 345 and a 346 as well.

Server error caused multiple posts.

ok?

I'm not sure if it would be a mobo problem or not...

The 345 had a mobo warranty recall quite some time ago for CPU VR issues so don't rule out a mobo problem on the 345.

The 346 did have some factory CPU mismatch issues so I would go down that path first on it.
