This is kind of strange because [2] has already passed that test numerous times. I'll recalibrate my cluster and run the test again. Besides that, [1] does the job Regards, Gregory On Monday, 10 July 2017 06:07:45 IDT Gregory Etelson wrote: Hello Ferruh, I could not reproduce server crash with the patch. However, some tests report ixgbe_vf_pmd and i40e_vf_pmd do not receive and transmit frames after process restart, although PMD initialization completed successfully Is there a way to collect PF firmware dump for investigation ?
