I am going off the code in
        arch/x86/kernel/cpu/perf_event_intel.c
(current git tree)

SNB and HSW have as a constraint
        INTEL_EVENT_CONSTRAINT(0x48, 0x4), /* L1D_PEND_MISS.* */

IVB has as a constraint
        INTEL_UEVENT_CONSTRAINT(0x0148, 0x4), /* L1D_PEND_MISS.PENDING */
        
Notice the difference.  Not sure if this is a bug in the kernel or what, 
but that's what's there and I think it's what's causing the issue.
