CentOS is a rebuild of the sources used to create RHEL and aims to reproduce RHEL bug for bug and feature for feature. Please file a ticket against the kernel package at bugzilla.redhat.com and let them know about the regression. If/when RH fixes it and releases a patched version, CentOS will pick it up automatically. For easier tracking, please crosslink this bug with the one opened at bugzilla.redhat.com. |

@manuelwolfshant I'm not sure how to crosslink ,but the redhat bugzilla id is 1902516 | |
Addendum : This seems to only affect mellanox cards with fw < 14.20. Anything that version and higher works fine | |
