This has "Not tainted" which would indeed rule out forced loading. So much for that idea :/ > http://www.users.on.net/~arthur.marsh/20150708470.jpg And that one has a bunch of NMI prints, curious those. But given Mathieu made them return NULL, that completely rules out the most interesting races. You could have a look at Documentation/networking/netconsole.txt and see if you can get that working between your machines; if you can get that to work you can maybe stop looking for that null-modem bit. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
