hm, you dont seem to have PREEMPT_RT enabled in your .config - it's set 
to PREEMPT_DESKTOP (config-2.6.12-RT-V0.7.51-11.0). OTOH, your 49-01 
config has PREEMPT_RT enabled. So it's not an apples to apples 
comparison. Just to make sure, could you check 51-11 with PREEMPT_RT 
enabled too?

i have just done a jack_test4.1 run, and indeed larger latencies seem to 
have crept in. (But i forgot to chrt the sound IRQ above the network 
IRQ, so i'll retest.)
