For example, ohci1394 had them for ages but they didn't work as expected before 2.6.20. What's more, ohci1394's resume routine alone is insufficient; an additional facility in ieee1394 was necessary and added for 2.6.21(-rc). This shows that the original authors of ohci1394's .suspend and .resume didn't test with actual external devices or gave up when they figured that the problem reaches into upper subsystem layers. (We still haven't tested interaction with most of the IEEE 1394 high level.) -- Stefan Richter -=====-=-=== --=- -=-== http://arcgraph.de/sr/ - 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/
