If you have an Oracle Quad 10Gb or Dual 40Gb Ethernet Adapter or an Oracle Quad Port 10GBase-T Adapter PCIe card installed in SPARC M8 or T8 system, with a VF assigned to the root domain, shutting down the root domain using the -f option, and then shutting down the IO domain with the -f option causes a panic of the IO domain.
Workaround
Avoid using the -f option with the ldm stop command in these circumstances.
Recovery
Reboot the IO domain.
