The panic message :

================================================================
IOMMU fault virtual address 0xc3000000
panic: pcib: uncorrectable DMA error AFAR 0xad6000 AFSR 0x210000ff00000000
syncing disk, buffers remaining ...
===================================================================

The nmap was a simple stealth scan with os fingerprinting :

nmap -sS -O <sun_blade_100_target>

The same error ocurred using ping with a big icmp packet (10,000 bytes).
In this case the panic message was :

================================================================
IOMMU fault virtual address 0xc3000000
panic: pcib: uncorrectable DMA error AFAR 0xad6000 AFSR 0x410000ff00800000
syncing disk, buffers remaining ...
===================================================================
