I totally ran into this issue here. https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1643558 It seems another contributor ran into this. Are you deploying using Kolla? On Tue, Mar 26, 2019 at 1:29 PM Massimo Sgaravatto <massimo.sgaravatto@gmail.com> wrote:
Hi
Did someone try using DELL M640 with BCM57840 network card as compute nodes ?
I am asking because we are adding a new compute node with such hw configuration to our OpenStack Ocata installation (with CentOS 7.6).
Each tiime we create a VM on this compute node, the compute node crashes (bnx2x_panic_dump). Not clear which specific event triggers the problem.
It doesn't seem a hw problem (e.g. iperf works without problems).
We are using the same network card, but on different servers (e.g. on some M630 systems).
If we disable the tx-checksum-ipv4 on the data network interface (i.e. "ethtool -K em3 tx-checksum-ipv4 off") we don't see anymore the problem.
Thanks, Massimo
