Sun Fire T2000/Netra T2000 systems running Solaris 10 with patch 118833-25 or later may hang during a reconfiguration boot if an external serial device is attached to the system.

This issue can occur on the following platforms:

• Sun Fire T2000/Netra T2000 systems running Solaris 10 with patch 118833-25 or later and without patch 126303-02

Notes:

1. Solaris 8 and Solaris 9 are not affected by this issue.
2. Solaris on the x86 platform is not affected by this issue.
3. This issue will only occur if an external serial device is attached to the system.

Should the described issue occur, the system may hang during a reconfiguration boot if an external serial device is attached.

Additionally, the serial device may not be able to interact with the system after a non-reconfiguration boot and commands such as prtconf(1M), prtdiag(1M) etc. may hang.

A kernel crash dump generated from such a hang will contain a thread with a stack trace similar to the following:

    pci_get_msi_ctrl+0x120()
    pci_msi_get_supported_type+0x1c()
    px_intr_ops+0x30()
    pxb_intr_ops+0xe0()
    pxb_intr_ops+0xe0()
    pxb_intr_ops+0xe0()
    ebus_intr_ops+0x190()
    i_ddi_intr_get_supported_types+0x50()
    ddi_intr_alloc+0x40()
    ddi_get_iblock_cookie+0x40()
    asyattach+0x3bc()
    devi_attach+0xac()
    attach_node+0x9c()
    i_ndi_config_node+0x104()
    i_ddi_attachchild+0x38()

    config_immediate_children+0xd0()
    devi_config_common+0xc0()
    mt_config_thread+0x60()
    thread_start+4()

Note: To force a panic to obtain the crash dump, send a break from ALOM.
