Regardless whether swap is on or off and whether ieee1394 and ohci1394 are loaded or not, it always behaves the same. It does something, then ends up with power LED off but a non-blinking cursor, i.e. _, still shown on the text console. Is this good or bad? Note, I didn't try to resume and won't, because I'm out of spare time. Perhaps I resurrect two older PCs I have here and set them up for hibernation sometime during the coming weeks. But although the words regression and FireWire meet here, I am so far not inclined to make this my problem. Note, the only post-2.6.22 patch to the ieee1394 subsystem which is directly related to power management went in before 2.6.23-rc1: "Freezer: make kernel threads nonfreezable by default" http://me.in-berlin.de/~s5r6/linux1394/merged/in_2.6.23/freezer-make-kernel-threads-nonfreezable-by-default.patch (Apart from using git, all 2.6.23 patches to ieee1394 and firewire can be seen at http://me.in-berlin.de/~s5r6/linux1394/merged/in_2.6.23/.) -- 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/
