https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=211713 --- Comment #51 from Warner Losh <imp@FreeBSD.org> --- You might try hw.nvme.enable_aborts=1 in loader.conf. This will enable aborting the command on timeouts when there's no fatal error indicated. This might help. Also, r331046 has a workaround suggested by Jim Harris. IF there's no fatal error signaled, we'll poll the completion queue. If that works, we move on (with a loud printf that will likely have a performance issue, but we'll see it). If not, and no fatal error signaled and aborts are enabled, we'll abort the command. Otherwise we'll reset the card (the current behavior). I could never recreate this problem, despite buying the exact card (I think) that others have reported as being bad. So, if you can reproduce this problem, please try r331046 or later and let me know if that helps or not. -- You are receiving this mail because: You are the assignee for the bug.
