Hi Luis,
We've tested now the proposed kernel 3.19.0-22 on Vivid and the virtual fibre channel is working and it's usable.

There is one error message that we see when checking the multipath
support, will send an update once that gets clarified on our end.

Status in linux source package in Wily:

Bug description:
  System details:
  Linux version 3.19.0-11-generic (apw@gloin) (gcc version 4.9.2 (Ubuntu 4.9.2-10ubuntu12) ) #11~lp1423343v201503311833 SMP Tue Mar 31 17:40:01 UTC 2015 (Ubuntu 3.19.0-11.11~lp1423343v201503311833-generic 3.19.3)

  Ubuntu 3.19.0-11
  Ubuntu Vivid 15.04 64bit custom kernel
  Platform: WS2012R2

  Using a fiber channel disk partition ( dev/sde1 in this example) outputs the following error:
  ​
  [ 1307.744496] blk_update_request: critical target error, dev sde, sector 0
  [ 1396.052488] blk_update_request: critical target error, dev sde, sector 0
  [ 1456.216570] blk_update_request: critical target error, dev sde, sector 0

  Creating a partition works, reading too, but first time writing it
  hangs for around 20 seconds and after a couple more writes the
  partition goes into read-only mode:

  #echo "test1" > test1.txt
  *hangs for 30 seconds*
  blk_update_request: critical target error, dev sde, sector 0
  # echo "test2" > test2.txt
  blk_update_request: critical target error, dev sde, sector 289671192
  Aborting journal on device sde1-8.
  EXT4-fs error (device sde1): ext4_journal_check_start:56: Detected aborted journal
  EXT4-fs (sde1): Remounting filesystem read-only
  # echo "test string" > sample.txt
  -bash: sample.txt: Read-only file system

  
  Dmesg log:
