https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D270966 --- Comment #18 from Ra=C3=BAl <raul.munoz@custos.es> --- (In reply to Santiago Martinez from comment #16) Hi Santiago, never thought it can be processor related, I've seen this problem on a 3700= x. Two hundred successful reboots? looks like too much without problems. I'll try on a 'AMD Ryzen 9 5950X 16-Core Processor'. About strange behavior after reboot, on that 3700x, changing lots of times sleeping time between pooling on a Mellanox mlx5 VF from a linux guest (ubu= ntu 22.04 with nvidia ofed driver, dpdk 23.03), the adapter stop working after a bhyve host reboot. That reboot was not related to that interface, was worki= ng fine. After reboot, no errors at all, neither on PF or VF, but no ping anywhere. Rebooting again didn't solve it, reset button did. Something happ= ened that needed 'hardware' reset. Nics nowadays are too smart and alive XD. May= be something more to consider on this problem?. --=20 You are receiving this mail because: You are the assignee for the bug.=
