Hi,

I'm finished with the bisect and the following commit will fix this
issue:

dc45708ca9988656d706940df5fd102672c5de92 [storvsc: Set the SRB flags
correctly when no data transfer is needed]

Looks like we'll want to include this patch.

Here's the rest of my bisect log, in case you're interested:

Title:
  [Hyper-V] Fiber Channel critical target error

Status in linux package in Ubuntu:
  Confirmed

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:
  [  461.284362] blk_update_request: critical target error, dev sde, sector 0
