Hi, sorry for the delayed response...

It does indeed go faster, and it seems a little bit more reliable, but with big enough transfers it locks up too. See commandline-2.txt and vmstat-2.txt - it gets through around 600-700MB before locking up. I also noticed that at 3-4 points during the transfer it seemed to "pause", and then continue. > Ok but can you set correctly the link with the command which was told > to fail in you first mail ? The patch could fix it. Yes, indeed: doing "ethtool -s eth0 speed 10 autoneg off" switches it to the slow speed, and keeps it there too (at 10Mb/s). "ethtool eth0" still reports "Advertised auto-negotiation: Yes" and "Auto-negotiation: on", which is probably not right. It also reports "Advertised link modes: 10baseT/Full" only, which is probably correct. It only actually restarts auto-negotiation when I issue the command "ethtool -s eth0 autoneg on", at which point the speeds goes back up to 1000Mb/s - the expected behaviour. So it seems ethtool works better than before wrt auto-negotiation. > Can you try something like: > dd if=/dev/zero bs=1024k count=1000 | ssh -c blowfish hell dd > of=/tmp/1000m.bin Well this transfer (from shuttle -> hell) completed successfully. See commandline-3.txt and vmstat-3.txt; However I noticed the speed was only around 7 MB/s and wondered if the link speed was maybe set to 100Mb/s, so I immediately afterwards did a "wget"-test again, which locked up after only 5%. The wget test however did confirm the link speed to be 1000Mb/s. See commandline-4.txt and vmstat-4.txt for that last, short test. > May I assume that the freeze locks everything (keyboard, mouse, led) beyond > the scp command itself ? Yes indeed. My (usb) keyboard doesn't respond at all anymore, networking is completely out, (usb) mouse freezes too. SysRq doesn't seem to help much either. -- Mourad
