Linux Kernel - Version: 4.4

Linux x86-64

Symptoms

You are running Oracle Enterprise Linux Release 4 Update 7 (OEL4 U7) or Enterprise Linux 5 Update 2 (OEL5 U2).

The system contains dedicated EDAC hardware, such as Intel 5000 Memory Controller found in a Dell PowerEdge M600 Blade server.

Every second, entries such as the following are reported in the /var/log/messages and ultimately the system hangs:

Apr  8 11:47:53 usellx78 kernel: EDAC i5000 MC0: NON-FATAL ERRORS Found!!! 1st NON-FATAL Err Reg= 0x800
Apr  8 11:47:53 usellx78 kernel: EDAC i5000:    NON-Retry  Errors, bits= 0x800

Low-level hardware diagnostics fail to reveal any memory hardware issues.

Changes

You have recently installed or upgraded the system to Enterprise Linux 4 Update 7 (OEL4 U7) or Enterprise Linux 5 Update 2 (OEL5 U2).
