It is unlikely that getting those specific machines to Cambridge will prove helpful, unless one of those systems exhibits the problem with great regularity. I have seen that problem happen on quite a few machines - but it happens very infrequently, always on a power-up, and it always goes away when you completely reset the EC by removing the battery and AC. It is quite possible that fixing http://dev.laptop.org/ticket/4397 will make the problem go away. The technique that the kernel currently uses to reboot involves forcing a triple-fault, which results in the main CPU resetting without the EC's knowledge. There is a 2-line patch in the ticket; it makes the kernel reboot using the approved EC interaction. I have been trying for 2 months to get this fix included in the kernel, but so far I haven't managed to get any traction. _______________________________________________ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
