A platform specific firmware issue on the Sun Fire T1000 and Sun Fire T2000 systems may cause systems to halt abruptly, resulting in a loss of service. Certain system events which should be resumable are incorrectly handled by firmware, causing the system to panic. A hardware failure may be incorrectly implied, leading to misdiagnoses and unnecessary FRU replacement.

This issue can occur on the following platforms:

• Sun Fire T1000/T1000+ systems with firmware prior to 6.1.11 (without patch 122431-04)
• Sun Fire T1000/T1000+ systems with firmware prior to 6.2.4 (without patch 123481-02)
• Sun Fire T2000/T2000+ systems with firmware prior to 6.1.11 (without patch 122430-04)
• Sun Fire T2000/T2000+ systems with firmware prior to 6.2.4 (without patch 123482-02)

To determine the firmware revision on the system, the following command can be run from the System Controller CLI:

    sc> showhost
    System Firmware 6.2.4 Sun Fire[TM] T1000 2006/08/18 12:37

Typical symptoms that have been observed include messages similar to the following:

    panic: PCI Fabric Error

    panic: Unrecoverable Hardware Error

There is no workaround for this issue. Please see the Resolution section below.

This issue is addressed on the following platforms:

• Sun Fire T1000/T1000+ systems with patch 122431-04 or later
• Sun Fire T1000/T1000+ systems with patch 123481-02 or later
• Sun Fire T2000/T2000+ systems with patch 122430-04 or later
• Sun Fire T2000/T2000+ systems with patch 123482-02 or later
