I've had exactly the same problem on my F13 machine. I never had that problem before, but since I upgraded to F13 my machine just freezes when I scp any big file. I've setuped a rescue kernel and configured kdump but the machine just "freezes" and no rescue is there. My machine is fully updated too

I have had a problem with kernel freezes for several months. It started when I first moved to the 2.6.31 kernel on Fedora 12. At that time it was relatively infrequent. When the 2.6.32 kernel came out, the problem became very bad -- every night when cron.daily runs the kernel would hang. Note that
