Mike,

Which test were you running? Because I'm not seeing it
on our x3550 M3..

-rt11 did not trip up just idling along like a couple earlier releases
did, but did stall when I tried to run ltp realtime testcases.

But please note that if your realtime workload is CPU-bound with prio
greater than that of RCU_SOFTIRQ, stalls would be expected.

							Thanx, Paul
