bnxt_en NIC driver crashes IO_PAGE_FAULT

Asked by aft2d on 2021-06-03

Hi all,

We received a bunch of new servers with a Supermicro H12SSL-NT mainboard that has an embedded Broadcom BCM57416 NIC.

On all those servers we observe crashes of the NIC driver (bnxt_en) from time to time. We're not able to manually reproduce this issue, it just occurs at some point. Also our monitoring does not show any irregularities(DDoS or sth. like this).


All servers are running with up-to-date packages:
$ lsb_release -rd
Description: Ubuntu 20.04.2 LTS
Release: 20.04
$ uname -r
5.4.0-73-generic ### It also happened on older kernel versions. The oldest we tried was 5.4.0-66.74

Thanks in advance.

If you use a different kernel is it different?

1. create a bug report (against "linux")
2. try switching to the hwe kernel (by installing linux-image-generic-hwe-20.04 or linux-generic-hwe-20.04, kernel version 5.8.*)

Can you help with this problem?
