Ehci Bios Handoff Failed" Message Appears - Oracle Sun Fire X4170 M2 Product Notes

Known Issues
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. There is a known
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

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.
