6256581 System got a hang or a panic with dtrace+kmdb

6264573 unanchored dtrace_getpcstack is rather imprecise toward function end
6289517 dtrace doesn't like fd_intr anymore 
6291378 dtrace helpers can interfere with the use of kmdb     
6295554 dtrace doesn't report errors in ERROR probes
6311947 add umod()/ufunc()/usym(), mod()/func()/sym()
6311952 buffered handler should be called after printing each tuple element
6311956 drops induced by END are not recorded
6311958 should indicate missing jstack() frames due to string table overflows
6311960 allow some DTrace options to be set dynamically
6311963 jstack() produces stacks packed with "StubRoutines"
6311975 allow boolean DTrace options to be unset
6315028 allow quantize()/lquantize() increments to be D expressions
6315033 add dtrace_addr2str()/dtrace_uaddr2str() to libdtrace API
6315034 add ucaller variable
6315035 enablings containing USDT probes are not dynamically reevaluated
6315037 cannot aggregate on the return value of some subroutines
6315039 including <sys/kstat.h> in a D script induces compile-time error
6315087 stack() not correctly printed for 32-bit consumers on amd64 kernel
6315975 flowindent should operate on any probe ending in "-entry"/"-return"
6317350 symbol tables should not be discarded for UNDEAD processes
