https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D232142 Jason Wolfe <j@nitrology.com> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |j@nitrology.com --- Comment #4 from Jason Wolfe <j@nitrology.com> --- This looks like it could an interoperability issue with a new firmware and = an old driver, we ran into this at Limelight. They moved over from outputting speeds in mb to kb I believe it was, so the old driver gets confused if run= ning a newer firmware. What's the sysctll output of dev.t5nex.0.firmware_version ? If you are hitt= ing this bug you have 2 options: - Upgrade to a newer driver. It looks like you are running the newer versio= n of pfsense w FreeBSD 11.2, so it'd take you pulling the new driver into the 11= .2 tree, and likely reverting a bunch of the tie in the driver has with the re= st of the kernel, like the epoch and TLS changes. This could get rough, but we= did test this and it's doable. - Downgrade the firmware to one that's compatible with the driver. The bina= ry firmware blob is actually included in the driver, but by default it will on= ly upgrade the firmware on the card if it's newer. If you set hw.cxgbe.fw_install=3D"1" in loader.conf, that tells the driver it's allowe= d to downgrade the firmware also. Give this a try if you'd like. --=20 You are receiving this mail because: You are the assignee for the bug.=
