Title:
thunderx nics fail to establish link
Status in linux package in Ubuntu:
In Progress
Status in linux source package in Xenial:
Fix Committed
Bug description:
[Impact]
When connected to certain switches, Cavium ThunderX nodes will occasionally
fail to establish a link. On one setup (using a Cisco 10G switch), we're seeing
a failure rate of about 20%.
Manually reloading the driver modules - or rebooting - is required to
recover.
A fix is now available in linux-next that greatly reduces (though it
doesn't 100% eliminate) the frequency of occurrences (2% vs. 20%, in
my case). Investigation continues to identify a resolution for the
remaining cases.
[Test Case]
Connect Cavium ThunderX systems to a known bad switch, and put them in a
reboot loop. In my test, I use the maas cli to release/acquire/deploy systems,
and wait for a node to enter the deployment failure state.
[Regression Risk]
The fix is upstream, and internal to a specific driver only used on Cavium
ThunderX systems.
