I will continue to narrow the cause down. It's as I suspected: "ieee1394: nodemgr: switch to kthread api, replace reset semaphore" http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff_plain;h=d2f119fe319528da8c76a1107459d6f478cbf28c Before that, I get a selfID-complete event, then nodemgr starts its work. After that its the reverse, which lets nodemgr inject a packet before the bus is completely ready. (So it's actually a regression in ieee1394 core's high-level functions, not in ohci1394. And it's harmless.) I will post when I have a fix. -- 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/
