Could you please test the following, each one separately? A. Configure PCI_MULTITHREAD_PROBE=n B. Revert patch "Initialize ieee1394 early when built in" http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff_plain;h=8df4083c5291b3647e0381d3c69ab2196f5dd3b7 I don't see how any other ohci1394 patch after 2.6.18 could lead up to that message. I also don't understand what causes this glitch. At least it seems recoverable, according to the "Host added" lines. -- 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/
