Bug ID 19236137
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
Sun Quad Data Rate (QDR) InfiniBand Host Channel Adapter PCIe option card (X4242A)
Solaris 10 Update 11
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.
