Wed Dec 14 18:05:08 CET 2011
Architecture: sparc64
Machine: sparc64

Running a full atf test on a -current sparc64 machine with a LOCKDEBUG
kernel results in:

panic: kernel diagnostic assertion "curcpu()->ci_mtx_count == 0" failed: file 
"../../../../kern/kern_softint.c", line 547 softint_execute: ci_mtx_count (-1) 
!= 0, sh_func 0x12bd9a0
db{0}> bt

The other cpu was idle in this case.
