This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed- yakkety' to 'verification-done-yakkety'. If the problem still exists, change the tag 'verification-needed-yakkety' to 'verification-failed- yakkety'.
If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed.

Adapter shows online till pettitboot and even Luns are also vissible in pettitboot. once selecting the OS from pettitboot and booting into it, it produces call traces and also few lpfc errors. attached the comple console logs FYR. The FC switch to which the Redfish adapter is connected is a 16 GB switch and the adapter is of 32 GB. According to me this parameter should not have any concern as the adapter has to support backward compatibility. ---Steps to Reproduce--- 1. install the adapter in a server. and connect it to FC switch (16 GB) 2. create zone and assign the LUNS to it from V7000. 3. reboot the OS root@ltciofvtr-firestone1:~# ll /sys/class/fc_host/ total 0 drwxr-xr-x 2 root root 0 Jan 25 04:22 ./ drwxr-xr-x 72 root root 0 Jan 25 03:50 ../ lrwxrwxrwx 1 root root 0 Jan 25 04:13 host10 -> ../../devices/pci0001:00/0001:00:00.0/0001:01:00.1/host10/fc_host/host10/ lrwxrwxrwx 1 root root 0 Jan 25 04:13 host6 -> ../../devices/pci0000:00/0000:00:00.0/0000:01:00.0/host6/fc_host/host6/ lrwxrwxrwx 1 root root 0 Jan 25 04:13 host8 -> ../../devices/pci0000:00/0000:00:00.0/0000:01:00.1/host8/fc_host/host8/ lrwxrwxrwx 1 root root 0 Jan 25 04:13 host9 -> ../../devices/pci0001:00/0001:00:00.0/0001:01:00.0/host9/fc_host/host9/ root@ltciofvtr-firestone1:~# root@ltciofvtr-firestone1:~# cat /sys/class/fc_host/host6/port_state Offline root@ltciofvtr-firestone1:~# cat /sys/class/fc_host/host8/port_state Offline root@ltciofvtr-firestone1:~# cat /sys/class/fc_host/host9/port_state Online root@ltciofvtr-firestone1:~# cat /sys/class/fc_host/host10/port_state Online root@ltciofvtr-firestone1:~# root@ltciofvtr-firestone1:~# lspci -nn | grep -i fibre 0000:01:00.0 Fibre Channel [0c04]: Emulex Corporation Lancer Gen6: LPe32000 Fibre Channel Host Adapter [10df:e300] (rev 01) 0000:01:00.1 Fibre Channel [0c04]: Emulex Corporation Lancer Gen6: LPe32000 Fibre Channel Host Adapter [10df:e300] (rev 01) 0001:01:00.0 Fibre Channel [0c04]: Emulex Corporation Lancer-X: LightPulse Fibre Channel Host Adapter [10df:e200] (rev 10) 0001:01:00.1 Fibre Channel [0c04]: Emulex Corporation Lancer-X: LightPulse Fibre Channel Host Adapter [10df:e200] (rev 10) root@ltciofvtr-firestone1:~# Device driver error code: [ 537.317563] lpfc 0000:01:00.1: 1:0338 IOCB wait timeout error - no wake response Data x3c [ 537.317755] lpfc 0000:01:00.1: 1:(0):0727 TMF FCP_LUN_RESET to TGT 1 LUN 0 failed (0, 0) iocb_flag x206 [ 537.317934] lpfc 0000:01:00.1: 1:(0):0713 SCSI layer issued Device Reset (1, 0) return x2007 [ 537.318005] lpfc 0000:01:00.1: 1:0372 iotag x0 is out off range: max iotag (x880) [ 551.653563] lpfc 0000:01:00.0: 0:(0):0748 abort handler timed out waiting for abortng I/O (xri:x149) to complete: ret 0x2003, ID 1, LUN 1 [ 551.653795] lpfc 0000:01:00.0: 0:0372 iotag x0 is out off range: max iotag (x880) [ 598.757557] lpfc 0000:01:00.1: 1:0338 IOCB wait timeout error - no wake response Data x3c [ 598.757766] lpfc 0000:01:00.1: 1:(0):0727 TMF FCP_LUN_RESET to TGT 1 LUN 1 failed (0, 0) iocb_flag x206 [ 598.757946] lpfc 0000:01:00.1: 1:(0):0713 SCSI layer issued Device Reset (1, 1) return x2007 [ 598.758017] lpfc 0000:01:00.1: 1:0372 iotag x0 is out off range: max iotag (x880) [ 613.093562] lpfc 0000:01:00.0: 0:(0):0748 abort handler timed out waiting for abortng I/O (xri:x14f) to complete: ret 0x2003, ID 1, LUN 0 [ 613.093630] INFO: task systemd-udevd:1148 blocked for more than 120 seconds.

[ 613.093659] systemd-udevd D 0 1155 1141 0x00040002 Hi Canonical, Can you please include these 2 commits to the lpfc driver on 17.04 and 16.04 HWE ? They've just been applied on mainline as of 4.11-rc1. The first resolves this problem, and the second prevents cache/DMA consistency problems which is likely to be hit in the future with this higher-performance adapter. I already asked for both patches to be flagged for stable kernels.
