Here is some info reported by the Solaris 2.x tool fpversion :

fpversion
 A SPARC-based CPU is available.
 Mbus module's clock rate appears to be approximately 60.2 MHz.
 Kernel says Mbus module's clock rate is 60.0 MHz.
 Kernel says main memory's clock rate is 50.0 MHz.

 Sun-4 floating-point controller version 0 found.
 A TI TMS390Z50 SuperSPARC chip (FAB 3.x or later) is available.
 A TI TMS390Z55 SuperCache appears to be present.
 FPU's frequency appears to be approximately 58.3 MHz.

 Use "-xtarget=ss20/61" code-generation option.

whilst dmseg under Solaris 2.x reports :
pac: enabled - SuperSPARC/SuperCache
cpu0: TI,TMS390Z55 (mid 8 impl 0x0 ver 0x3 clock 60 MHz)
mem = 65536K (0x4000000)
avail mem = 61116416

I can get another crash dump for this problem if you want, for a 
generic scsi3 1.2 kernel, but where should I upload it to?
