One in the middle of USB related messages with no FireWire stuff around (17:25:19 to 17:25:44). The other with parport, ieee1394, USB messages around it (17:25:44 to 17:26:31). From there, the last 17:25:44 message is strange: The device 00110666000013cc which is the controller is reported as being removed. Chris, did you do something at this point? Also, in http://lkml.org/lkml/2008/6/1/2 you reported a patch which changes the SCSI core's interaction with the driver core as first bad commit. Did you check that going before this commit removes _all_ the pauses, even those around USB or FireWire messages? Or did you only check whether disk drives appear quickly? -- 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/
