Legacy PCIe Hot-Plug Is Not Supported by SLES10 SP2

Issue:

SLES10 SP2 is not able to do legacy hot-plug on the Sun Blade X6270 Server

Module. During boot up the kernel loads the PCIE_AER driver. This driver gains

native (pciehp) control of PCIe hot-plug slots using the BIOS/ACPI _OSC

method. After this occurs, the legacy (acpiphp) hot-plug driver should never be

loaded.

Affected Operating Systems and Software:

• SUSE Linux Enterprise Server 10 Service Pack 2 (SLES10 SP2)

• Supplemental Software Releases 1.0, 1.1, 1.2, 1.4, 2.0, 2.0.1, 2.1

Workaround:

You must use the pciehp hot-plug driver with SLES10 SP2 on the Sun Blade

X6270 Server Module.

The acpiphp hot-plug driver should not be used with SLES10 SP2 on the Sun

Blade X6270 Server Module.

• Red Hat Enterprise Linux (RHEL) 5.3

• Supplemental Software Releases 1.0, 1.1, 1.2, 1.4, 2.0, 2.0.1, 2.1

Workaround:

These error messages are benign and have no effect on the system stability or

performance.
