Subject: [Bug 156321] New: mpt3sas timeout with xen, works only with mpt3sas.msix_disable=1 (SAS3008 card)
Date: Thu, 08 Sep 2016 07:39:17 +0000 [thread overview]
Message-ID: <bug-156321-11613@https.bugzilla.kernel.org/> (raw)
https://bugzilla.kernel.org/show_bug.cgi?id=156321
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 (debian-kernel@lists.debian.org)
Hardware: x86-64
OS: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: Other
Assignee: scsi_drivers-other@kernel-bugs.osdl.org
Reporter: john.wyzer@gmx.de
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 :

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.
