Not if you want video to come back on most hardware - the kernel has no idea how to reinitialise your graphics card. s2ram and similar tools attempt to deal with this by reprogramming it from userspace. On the other hand, if it did work on the same hardware with earlier kernels, then that's a bug. -- Matthew Garrett | mjg59@srcf.ucam.org -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
