Hey Bryan

modprobe megaraid_sas max_sectors=2048

Doesn¹t seem to help either.


Same error.

Thanks
Adi

Title:
  Ubuntu 15.04 Install Error with Avago Controller

Status in linux package in Ubuntu:
  Triaged

Bug description:
  Hello Canonical Team

  We are running to an issue installing ubuntu PPC64LE 15.04 full blown
  image on our servers  (with RAID controller).  Installation hangs
  around 70% of progress.

  An important part of our configuration is Avago RAID controller:
  9361-8i Firmware version we used is 4.300.00-4429, and the package is
  24.10.0-0002.

  IMPORTANT: It has to be noted that with same hardware configuration
  14.10 full blown image installs fine.

  Dmesg logs are attached:

  Looking at dmesg logs point out that:
  LSI (avago) driver loads fine
  During further interaction with raid volume during the installation process, firmware errors are seen 
  [  196.991417] megasas: FW status 0x3

  [  196.999376] megasas: FW status 0x3

  [  197.007376] megasas: FW status 0x3
  Further down the  process I/O errors are thrown
  [  217.438664] Buffer I/O error on device sda2, logical block 22052864

  [  217.438671] Buffer I/O error on device sda2, logical block 22052865

  [  217.438678] Buffer I/O error on device sda2, logical block 22052866

  [  217.438686] Buffer I/O error on device sda2, logical block 22052867

  Full dmesg log is attached. Snippet is pasted below highlighting:

  It can be noted that there’s a Mellanox Connectx 3 pro card with some test Firmware on our setup. 
  We can Ignore any diagnostic messages from that card in dmesg logs for the purpose of this bug. 

  Thanks
  Adi Gangidi
