            Bug ID: 156321
           Summary: mpt3sas timeout with xen, works only with
                    mpt3sas.msix_disable=1 (SAS3008 card)
           Product: SCSI Drivers
           Version: 2.5
    Kernel Version: 4.6.0-1-amd64 ([email protected])
          Hardware: x86-64
                OS: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: Other
          Assignee: [email protected]
          Reporter: [email protected]
        Regression: No

At the moment I've only tested the kernel version cited above. The hardware in question is a SAS3008 card.

When I start the the machine without loading Xen, the mpt3sas driver works just fine.
When Xen is loaded, different timeouts occur during I/O.

For simplicity I'm citing the trace from
https://www-947.ibm.com/support/entry/portal/docdisplay?lndocid=migr-5099120 :

[Â Â 618.160182] mpt3sas0: _base_event_notification

I don't know if the trace is exactly the same but I remember the "base_event_notification: timeout".

As the bug report on ibm.com cited above mentions, booting with mpt3sas.msix_disable=1 solves the problem for the time being.

https://forums.servethehome.com/index.php?threads/lsi9211-8i-on-ubuntu-15-10-timeouts.8820/page-2
mentions the same problem in connection with Vmware ESXi.

Can you please try once with latest Phase13 SAS3008 HBA firmware.

Thanks,

Hi, Sreekanth!

I'm sorry - I was a bit too little specific:

The physical card in question is a "LSI 9300-8i". I took the SAS3008 from the lspci output which I considered to be more generic.

The firmware in used is the latest available from
http://www.avagotech.com/products/server-storage/host-bus-adapters/sas-9300-8i#downloads
which is P12 from April 2016.

--- Comment #3 from Sreekanth Reddy <[email protected]> --- Hi John,

Recently our FW team has fixed this type of issue in the Firmware. Maybe this fix went in the Phase13 FW. So you may need to wait to some more time until this Phase13 FW is available for outside.

Thanks,
Sreekanth

With the latest revision of the firmware (P13) this is no longer an issue.
