x86: Cannot Enable MPxIO (6664694)
x64 systems using the LSI SAS PCI-E host bus adapters (HBAs) such as SG-XPCIE8SAS-E-Z,
SG-XPCIE4SAS-Z, SG-XPCIE4SAS3-Z, and SG-PCIE8SAS-Z, cannot enable MPxIO if more
than 4 Gbytes of RAM is installed.
To conrm whether your system is aected, type the command prtpicl -v. Search the output
of this command for devices using either pci1000,56 or pci1000,58 compatible properties,
and where a pcie-capid-reg property exists and the revision-id property is less than or
equal to 2. For example:
pci1000,56 AND pcie-capid-reg exists AND revision-id <= 2
or
pci1000,58 AND pcie-capid-reg exists AND revision-id <= 2
Workaround: Download and install patch 125082-13 from http://sunsolve.sun.com.
64-bit SPARC: DR Operations Involving Lowest CPU ID
Fail (6663570)
Dynamic reconguration (DR) operations involving the lowest CPU ID might cause the
domain to panic. The following error message is displayed:
panic[cpu40]/thread=2a1008ebca0: BAD TRAP: type=10 rp=xxxxxxx addr=xxxxxxx mmu_fsr=0
Workaround: Do not use DR to identify the system board hosting the CPU with the lowest
CPU ID. Use the prtdiag command to identify the CPU with the lowest CPU ID.
