The Solaris 10 Update 11 installation might fail when the Sun Quad Data Rate (QDR)
InfiniBand Host Channel Adapter PCIe option card (X4242A) is installed.

Sun Fire X4170 M2 Server
Sun Fire X4270 M2 Server
Sun Quad Data Rate (QDR) InfiniBand Host Channel Adapter PCIe option card (X4242A)
Solaris 10

Cause

There is a known limitation for 64-bit addresses in PCIe with some cards installed and when running Solaris 10.

Solution

Oracle Solaris 10 1/13 does not support PCI Subsystem settings option enabled in the BIOS setup utility IO menu.

There is a known issue, for details see Sun Fire X4170 M2 and X4270 M2 Servers Product Notes 1.7.6.

Page 17,Known Issues;

Limitation on 64-bit addresses in PCIe with some cards installed and when running Solaris 10.
When booting Solaris 10 Update 11, the following error messages might be displayed:
NOTICE: unsupported 64-bit prefetch memory on pci-pci bridge (128/3/0)
NOTICE: hermon0: error during attach: UAR BAR mapping
NOTICE: hermon0: driver failed to attach: UAR BAR mapping
WARNING: kstat_create('unix', 0, 'hermon_rsrc_cache00000000'): namespace collision

The system might panic and the processor will be taken off line when the system is rebooted.

Affected hardware:
Sun Fire X4170 M2 Server
Sun Fire X4270 M2 Server
Sun Quad Data Rate (QDR) InfiniBand Host Channel Adapter PCIe option card (X4242A)
Solaris 10

Workaround:

In the BIOS Setup Utility, disable the PCIe 64-bit resource allocation (PCI MMIO 64 Bits
Support). The hermon driver for the Sun Quad Data Rate (QDR) InfiniBand Host Channel
Adapter PCIe option card (X4242A) will then load successfully.

Solution:

Update System to Solaris 11 or later.
