I copied the sysreq-t screen to paper and then typed it up and fed it to ksymoops. I get some errors since this kernel has module support turned off. I also get a message from ksymoops saying Warning (Oops_read): Code line not seen, dumping what data is available which I'm not sure of the meaning. So anyway, my oops file and the output from ksymoops follow. Hopefully I've done this right. If there is anything else I can provide let me know.
