Title:
[Regression] From 3.16.0-45 to -47: Intel IGB Tx Unit Hang network
adapter reset problem prevents stable network connection
Status in linux-lts-utopic package in Ubuntu:
Confirmed
Bug description:
Regression from at least:
linux-image-3.16.0-45-generic=3.16.0-45.60~14.04.1
to:
linux-image-3.16.0-47-generic=3.16.0-47.63~14.04.1
On an Intel Xeon Workstation with an Intel IGB Gigabit Ethernet
Adapter, the network connection is never stable, as the Adapter
regularly resets itself due to multiple Tx Unit Hangs (see attached
kernel log)
When booting the old kernel, the system works flawless again.
I can not use "ubuntu-bug linux" because it has no options and wants
to report only for the currently running kernel, which has no network
connection.
For some reason I can only attach one file. I chose to attach the
kern.log - the version.log shows only the currently running kernel,
and I can paste the lspci log later if required.
> lsb_release -rd
Description: Ubuntu 14.04.3 LTS
