https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D273372 Navdeep Parhar <np@FreeBSD.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |np@FreeBSD.org --- Comment #2 from Navdeep Parhar <np@FreeBSD.org> --- I tried 13.2 as well as 14.0-alpha3 on bare metal running 13.2 and 14.0-alp= ha3 inside bhyve VMs. The host creates VF devices from a T520 and passes them through -- one to each VM. The cxgbev VF driver inside the VM worked prope= rly in all cases. The only bug I ran into was the kernel creating unusable VFs for a card in a particular slot. It was fixed in https://cgit.freebsd.org/src/commit/?id=3D7063f94283af60818429a0c2d70e80ae4= ad5c146 That is not the root cause of this problem. Can you please try these to debug your problem further: 1. Reduce num_vfs to 2 or 4 (from 14) temporarily, for testing. 2. When the problem occurs, grab the device log _before_ attempting any ifconfig down/up. sysctl -n dev.t5nex.0.misc.devlog --=20 You are receiving this mail because: You are the assignee for the bug.=
