Interesting...for RTAI or Xenomai, <alt><tab> should not be able to bring the system down like that, unless there's something going on with SMI (the only thing AFAIK that can run at a lower level than RTAI or Xenomai on an x86 system). If this was on a preempt-rt system, that behavior is totally understandable. It is possible the <alt><tab> problem could represent the same issue I am seeing on the ARM. -- Charles Steinkuehler [email protected]
