I am running 2.6.26.6-rt11-1.2944.fc6.emulab-highmem #1 SMP PREEMPT RT
My test pgm is a java pgm that has about 650 threads in it (i am doing some stress testing). This test runs w/o any kernel messages when run on vanilla 2.6.25 kernel. But w/ the above RT kernel I see some kernel msgs that I do not understand.
ANy hints?
