I am not on this list, so hopefully someone could CC me if there is information that might be useful.

Not quite 2 weeks ago I sent in a series of what appeared to be random OOPS messages, not quite sure if it was hardware or software, hoping to find out which. I was asked by one person to recompile the kernel without preemption, which I did. The rate of OOPS has gone down dramatically since then, yet I did still get 1 OOPS with heavy machine use over about the last 2 weeks. Obviously there is no guarantee that it is related to preemption when it has still given one OOPS, and since the problem was random and I have had no way to repeat it even with the two other kernel versions (2.6.8 and the stock Fedora Core 2 kernel) that had this random problem on them.

I am sending in the one OOPS I did get. Unfortunately, I think it is incomplete, whatever the problem is, it seems to have caused the OOPS itself to have cut short. This kernel does have all debug information built into it so possibly it might help. I wanted to find out if a partial OOPS like this is at all useful; if not I'll have to wait till I get another OOPS.

I am sending the original OOPS set first, and at the end of this you will find the single new OOPS. Note that the system information such as modules and hardware will be the same on the new OOPS and old OOPS, all that differs is the kernel no longer containing preemption.

Machine is a dual P2-450 on 440BX chipset.
