Hello ,

Hi,
what is the server model and generation? i suspect this is something related to BIOS settings or with the OS support on this model server.
Refer Red Hat Enterprise Linux Certification and Support HP ProLiant & BladeSystem Server and ensure that this OS is supported(Click on Archive if you dont find your server in list)

OS is Linux 2.6.9-78
Server Model is HP Proliant DL 380 G5

How to trouble shoot this Kernel panic issue and resolve this ?
How we can prevent this error in future?

[Murali_V]

As per the matrix, I see that the minimum supported RHEL 4 update version is 5.
Update the Linux version and install latest HP ProLiant support pack.

I hardbooted the server and now the server is working fine.
Is this issue is caused because of any interrupt handler?
Normally two typer of kernel panic errors are there, hard panic and Soft panic.
How can i confirm regarding this?

[Murali_V]

From the information available it is difficult to understand what exactly caused this issue, This seems to be hard panic and to prevent this I suggest to update the Linux version, PSP and BIOS firmware.

Hi Dawn,

What is the kernel version?

Were there any changes made to the server?
Is this an application server?

Do you have diskdump configured for this server?

[dawn_jose85]

The Kernel version is 2.6.9-78.ELsmp
This is an application server .
Can you please let me know what u meant by diskdump. actually i didn't get that

The diskdump utility offers the ability to create and collect vmcore (Kernel dumps) on a single system without needing to be connected to a network. Diskdump creates files in an identical format to the netdump core files and can be analyzed with the same tools. Like netdump, diskdump will only work with certain hardware.

In RHEL 4 we configure diskdump and in RHEL 5 we configure kdump.

Refer below redhat KB article for more information on diskdump and its configuration.
