https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D211713 --- Comment #23 from tkurmann@gmail.com --- Progess! I updated the bios of the R720 to 2.5.4 and rebooted FreeBSD with the latest snapshot 12-CURRENT 20170309. To my surprise reading using dd works with any block size. The speed is capped at 2.0Gbytes/s, but it works. Writing on the other hand seems to only work up to a bs of around 512k (didn't find the threshold yet) and then it would timeout again. The speed cap made me suspicious and I checked to see what pcie version the card was running with (pciconf -lbace nvme0) and of course it was version 2.0. Under ubuntu 16.04= the card was reported with version 3.0 and the speed limit was 3.2 Gbytes/s. I assume this is related somehow, any thoughts? --=20 You are receiving this mail because: You are the assignee for the bug.=
