Yes, I agree. Like I said it definitely runs longer now than it did before, but unfortunately shows the same symptom. Here is a little more information that I gleaned last night which may or may not be useful. I noticed that arch/ppc/kernel/misc.S still had the (old?) assembly functions for doing atomic operations. They are similar but slighly different to the inline functions in atomic.h. I ran yesterday for about 4 hours with these "alternative" atomic functions, and I did not see the failure. I'm not sure if this was just a coincidence (the timing changed slightly), or whether it indicates a problem with the inline atomic functions. > Can we get an oops trace if you hit it ? For now I'm puzzled. Sure, I'll post it next time I get it. (I already cleared the one I got last night). Regards, Brian ** Sent via the linuxppc-embedded mail list. See http://lists.linuxppc.org/
