If you dont turn on PREEMPT_RT you'll get > an almost-vanilla kernel. 2.6.22-rc2, only EVENT_TRACE - boots, can't rerpoduce 2.6.21-vanila - can reproduce 2.6.21-rt7, trace options off - can reproduce 2.6.21-rt7, trace options on - can't reproduce Possibly something timing related, that's altered by the trace code. I tried the trace kernel without starting the trace app, but still no bug. Any other ideas?
