[...] Maybe a FireWire kernel driver bug could be the cause and USB a victim, by the FW driver corrupting memory and other kernel subsystems beginning to act strange. Or USB trouble was the cause and FireWire slowdown one result of it. (I don't know whether the above USB message is about the hardware doing something to the kernel, or the kernel doing something to the hardware. grep doesn't find the message in the source with the string fragments that I tried.) -- Stefan Richter -=====-==-== =--- -=-=- http://arcgraph.de/sr/ |
