Running RHEL 3.0 x86_64 U6 (2.4.21-37.Elsmp)
I have searched, logged a call with HP and Redhat support and have
turned up nothing. HP says I have memory problems, Redhat says it's a
known non-critical error.
I am not sure if I am chasing after the correct problem but all six of
my AMD64 HP XW9300 (based off Tyan Thunder K8WE?) with anywhere between
4-16Gb RAM and two Opteron CPU's get the following errors :
Nov 10 17:18:46 node4 kernel: CPU 0: Silent Northbridge MCE

Nov 14 19:14:16 node4 kernel: NB error address 00000000dffe0038
Five of the computers have between 1-30 references to these error
messages in the past 3 weeks. One computer has over 30,000 instances of
these error messages. I am getting the majority of these messages on
computers with >4Gb RAM but I have had the messages on computers with
only 4GB RAM.
The main reason I am focusing on these messages is that the computers
have crashed numerous times since being put online. The computer with
30K instances of the error message has crashed about 1-2 times per week.
I am running the latest BIOS.
I can not turn on diskdump since they have Nvidia SATA controllers (not
support by diskdump) and netdump has not produced anything since during
the kernel crash no data was written ( network driver went down? ).
Has anyone else seen these messages or have any idea how to identify the
problem? Could my crashes be due to Northbridge errors or am I barking
up the wrong tree.
