Mea culpa. I meant to say that I was transferring from f7 to the FC4 box.
From FC4, the command was:
scp pluto:/tmp/file.iso .

Thanks Andy. Good idea. I'll try that next shot.
Don't have an answer, just a confirmation that I have the exact same
problem here.
I'm running 2 FC6 boxes. Each has a VIA based motherboard, with the
on-chip NIC and a Nat Semi add on NIC. Got a mix of PATA and SATA
disks on both boxes.
I get random lockups on the machine that initiates the file transfer.
No panic, just a hard lockup. The receiving machine is still working fine.
I've got new cables, and a straight thru cable (bypassing my router),
and I've tried all combinations of NIC connections. Usually breaks at
some point (usually after a Gig or so has transferred). Small
transfers and other network traffic work fine.
CPU temp 25 - 30 C. I've got lots of fans!
I've learned to live with it.
Regards,
John
