Are there any kernel line parameters required for an HP xw9300 workstation installed with Red Hat Enterprise Linux 4?
The HP xw9300 workstation requires acpi=off
on the kernel command line in the /etc/grub.conf
file to properly support a Red Hat Enterprise Linux 4 Update 1 in a single or dual core configuration.
For Red Hat Enterprise Linux 4 Update 2, no kernel line parameters are required.
If you experience a problem with any other dual core system, typically a kernel panic during boot, you may want to try any or all of the following kernel line parameters in the /etc/grub.conf
file:
* Red Hat Enterprise Linux 4 Gold:
- dual core systems not supported
* Red Hat Enterprise Linux 4 Update 1:
- numa=off
- acpi=off
* Red Hat Enterprise Linux 4 Update 2 and beyond:
- pci=noseg
- pci=nommconf
Note: The above is not applicable to Red Hat Enterprise Linux 3, however, Update 5 is required for dual core support on the xw9300.
If you need to add any of the above options to the grub.conf
file, use the following example:
title Red Hat Enterprise Linux AS (2.6.9-11.EL)
root (hd0,0)
kernel /vmlinuz-2.6.9-11.EL ro root=LABEL=/ acpi=off console=ttys0
initrd /initrd-2.6.9-11.EL.img
Multiple kernel line parameters should be separated by a space. You will need to reboot the system in order for the changes to take effect.
