   the watchdog interrupt hit?

if you use "disassemble <address>", you can normally find it by
matching up the actual address given and the assembler code...
if you don't know sparc asm, send me the output from the disassemble
command and we'll figure it out...

BTW, do you have ddb configured?  you really should.  everyone who
runs SMP kernels should probably have DDB and it wouldn't be bad to
also turn on the LOCKDEBUG option to check that simplelock's are
correctly used ...
