https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=193152 Bug ID: 193152 Summary: mlxen driver problem (iSCSI issue) with MT26448 interface Product: Base System Version: 10.0-RELEASE Hardware: amd64 OS: Any Status: Needs Triage Severity: Affects Some People Priority: --- Component: kern Assignee: freebsd-bugs@FreeBSD.org Reporter: gnoma_86@gbg.bg Hello, I had problem using the driver mlxen from the ports tree. I built it in the kernel, tried also loading it dynamically, it's the same issue. When I start iSCSI daemon (tried ctld and istgt, same issue) I cannot connect to the iSCSI from the initiator and I got the following message in the syslog: Aug 29 11:15:19 sentinel kernel: WARNING: 10.0.80.2 (iqn.1991-05.com.unixhomenet:hola-pc): no ping reply (NOP-Out) after 5 seconds; dropping connection Aug 29 11:15:51 sentinel kernel: cfiscsi_ioctl_handoff: new connection from iqn.1991-05.com.unixhomenet:hola-pc (10.0.80.2) to iqn.sentinel.deltanews.lan:test123 Aug 29 11:15:58 sentinel kernel: WARNING: 10.0.80.2 (iqn.1991-05.com.unixhomenet:hola-pc): no ping reply (NOP-Out) after 5 seconds; dropping connection Aug 29 11:16:01 sentinel kernel: cfiscsi_ioctl_handoff: new connection from iqn.1991-05.com.unixhomenet:hola-pc (10.0.80.2) to iqn.sentinel.deltanews.lan:test123 Aug 29 11:16:21 sentinel kernel: WARNING: 10.0.80.2 (iqn.1991-05.com.unixhomenet:hola-pc): no ping reply (NOP-Out) after 5 seconds; dropping connection Aug 29 11:17:15 sentinel kernel: cfiscsi_ioctl_handoff: new connection from iqn.1991-05.com.unixhomenet:hola-pc (10.0.80.2) to iqn.sentinel.deltanews.lan:test123 Aug 29 11:17:20 sentinel kernel: WARNING: 10.0.80.2 (iqn.1991-05.com.unixhomenet:hola-pc): no ping reply (NOP-Out) after 5 seconds; dropping connection Also noticed some package lost: root@sentinel:/var/log # ping -f 10.0.80.2 PING 10.0.80.2 (10.0.80.2): 56 data bytes .............................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................^C --- 10.0.80.2 ping statistics --- 168461 packets transmitted, 167952 packets received, 0.3% packet loss round-trip min/avg/max/stddev = 0.020/0.031/0.360/0.011 ms root@sentinel:/var/log # switching iSCSI traffic, or testing the connection with flooding ping via standard Intel 1GB interface makes no trouble: root@sentinel:/var/log # ping -f 192.168.2.101 PING 192.168.2.101 (192.168.2.101): 56 data bytes .^C --- 192.168.2.101 ping statistics --- 44140 packets transmitted, 44139 packets received, 0.0% packet loss round-trip min/avg/max/stddev = 0.105/0.303/0.466/0.062 ms root@sentinel:/var/log # Building the last version of the driver provided by mellanox website (http://www.mellanox.com/downloads/Drivers/MLNX_EN_FreeBSD_v2.1.tgz) fixed the iSCSI issue, but flooding ping still reports some package loss. Also trying to load dynamically the driver from mellanox during boot using loader.conf seem to fail, so I had to put the kldload command in rc.local, or in /etc/rc.d/crld in order to assure it's being loaded at system boot and interface is configured before iSCSI target daemon starts. I can also provide tcpdumps if needed. -- You are receiving this mail because: You are the assignee for the bug.
