This makes things clearer and I think there is a problem with trap handling, as already mentioned in another email.
In case it helps. Notice that in x86 Linux does not treat a trap like an interrupt as it keeps the CPU interrupt bit status on and not cleared. So when the handler is reached intturrupts are enabled at the CPU level. That might be different on PPC and could make a difference. Just my penny.
