But after scp stalled the interface, iperf transfers fail, too. 0mb@milhouse:~$ iperf -c 192.168.4.2 -d ------------------------------------------------------------ Server listening on TCP port 5001 TCP window size: 85.3 KByte (default) ------------------------------------------------------------ ------------------------------------------------------------ Client connecting to 192.168.4.2, TCP port 5001 TCP window size: 96.0 KByte (default) ------------------------------------------------------------ [ 5] local 192.168.4.1 port 41558 connected with 192.168.4.2 port 5001 [ 4] local 192.168.4.1 port 5001 connected with 192.168.4.2 port 58296 [ ID] Interval Transfer Bandwidth [ 5] 0.0-10.0 sec 111 MBytes 93.0 Mbits/sec [ 4] 0.0-10.1 sec 105 MBytes 87.2 Mbits/sec 0mb@milhouse:~$ scp testfile mb.marge: Enter passphrase for key '/home/mb/.ssh/key':=20 testfile 12% 6912KB 1.8M= B/s - stalled -^testfile 12= % 6912KB 1.6MB/s - stalled -1mb@milhouse:~$ ^C 130mb@milhouse:~$ iperf -c 192.168.4.2 -d ------------------------------------------------------------ Server listening on TCP port 5001 TCP window size: 85.3 KByte (default) ------------------------------------------------------------ connect failed: No route to host dmesg is spammed with these messages: > [51069.954315] atl1c 0000:01:00.0: atl1c: eth0 NIC Link is Up<100 Mbps Fu= ll Duplex> > [51069.954409] IPv6: ADDRCONF(NETDEV_CHANGE): eth0: link becomes ready > [51155.933162] atl1c 0000:01:00.0: atl1c: eth0 NIC Link is Down > [51157.441946] atl1c 0000:01:00.0: atl1c: eth0 NIC Link is Up<100 Mbps Fu= ll Duplex> > [51276.049211] atl1c 0000:01:00.0: irq 46 for MSI/MSI-X > [51276.049371] atl1c 0000:01:00.0: atl1c: eth0 NIC Link is Up<100 Mbps Fu= ll Duplex> > [51290.233447] atl1c 0000:01:00.0: irq 46 for MSI/MSI-X > [51290.233641] atl1c 0000:01:00.0: atl1c: eth0 NIC Link is Up<100 Mbps Fu= ll Duplex> > [51305.025257] atl1c 0000:01:00.0: irq 46 for MSI/MSI-X > [51305.025419] atl1c 0000:01:00.0: atl1c: eth0 NIC Link is Up<100 Mbps Fu= ll Duplex> > [51323.305245] atl1c 0000:01:00.0: irq 46 for MSI/MSI-X > [51323.305405] atl1c 0000:01:00.0: atl1c: eth0 NIC Link is Up<100 Mbps Fu= ll Duplex> > [51338.393216] atl1c 0000:01:00.0: irq 46 for MSI/MSI-X > [51338.393375] atl1c 0000:01:00.0: atl1c: eth0 NIC Link is Up<100 Mbps Fu= ll Duplex> > [51350.739196] atl1c 0000:01:00.0: atl1c: eth0 NIC Link is Down > [51353.810485] atl1c 0000:01:00.0: atl1c: eth0 NIC Link is Up<100 Mbps Fu= ll Duplex> > [51376.817238] atl1c 0000:01:00.0: irq 46 for MSI/MSI-X > [51376.817399] atl1c 0000:01:00.0: atl1c: eth0 NIC Link is Up<100 Mbps Fu= ll Duplex> > [51391.425209] atl1c 0000:01:00.0: irq 46 for MSI/MSI-X > [51391.425371] atl1c 0000:01:00.0: atl1c: eth0 NIC Link is Up<100 Mbps Fu= ll Duplex> This did not happen with earlier kernels.
