Linus' current tree seems to trigger this in perf_event_open on startup:

                        if (value[ptr]!='0') fprintf(stderr,"Expected 0x\n");
                        ptr++;
                        if (value[ptr]!='x') fprintf(stderr,"Expected 0x\n");
                        ptr++;

I think it's from this..

/sys/bus/event_source/devices/cpu/events/mem-loads
event=0xcd,umask=0x1,ldlat=3

Looks like that field isn't always hex.
