wonko, could you please test the latest upstream kernel available from the very
top line at the top of the page (not the daily folder) following
https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional
upstream developers to examine the issue. Once you've tested the upstream
kernel, please comment on which kernel version specifically you tested. If this
bug is fixed in the mainline kernel, please add the following tags:
kernel-fixed-upstream
kernel-fixed-upstream-VERSION-NUMBER
where VERSION-NUMBER is the version number of the kernel you tested. For
example:
kernel-fixed-upstream-3.16-rc1
This can be done by clicking on the yellow circle with a black pencil icon next
to the word Tags located at the bottom of the bug description. As well, please
remove the tag:
needs-upstream-testing
If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-VERSION-NUMBER
As well, please remove the tag:
needs-upstream-testing
Once testing of the upstream kernel is complete, please mark this bug's
Status as Confirmed. Please let us know your results. Thank you for your
understanding.

Bug description:
we have a problem with Dell PowerEdge machines, having the Broadcom
5720 chip. We have this problem on generation 12 systems, across
different models (R420, R620), with several combinations of bios
firmwares, lifecycle firmwares, etc... We see this on several versions
of the linux kernel, ranging from 3.2.x up tot 3.11, with several
versions of the tg3 driver, including a manually compiled latest
version (3.133d) loaded in a 3.11. The latest machine, where we can
reproduce the problem has Ubuntu Precise installed, but we also see
this behaviour on Debian machines. We run Xen on it, running HVM hosts
on it. Storage is handled over iSCSI (and it is the iSCSI interface we
can trigger this bug on in a reproducible way, while we have the
impression it also happens on other interfaces, but there we don't
have a solid case where we have e reproducible setup).
All this info actually points into the direction of the tg3 driver
and/or hardware below it not handling certain datastreams or data
patterns correctly, and finally crashing the system. It seems
unrelated to the version of kernel running, xen-version running,
amount of VM's running, firmwares and revisions running, etc...
We have been trying to pinpoint this for over a year now, being unable
to actually create a scenario where we could reproduce this. As of
this week, we finally found a specific setup where we could trigger
the error within a reasonable time.
The error is triggered by running a certain VM on the Xen stack, and
inside that VM, importing a mysqldump in a running mysql on that VM.
The VM has it's traffic on an iSCSI volume, so this effectually
generates a datastream over the eth1 interface of the machine. Within
a short amount of time, the system will crash in 2 steps. We first see
a timeout on the tg3 driver on the eth1 interface (dmesg output
section attached). This sometimes repeats two or three times, and
finally, step 2, the machine freezes and reboots.
While debugging, we noticed that the bug goes away when we disable sg
offloading with ethtool.
If you need any additional info, feel free to ask.
