https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D234766 Eric Joyner <erj@freebsd.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |erj@freebsd.org --- Comment #3 from Eric Joyner <erj@freebsd.org> --- (In reply to Henry David Bartholomew from comment #2) I was going to post a comment about how setting that tunable doesn't really cause any other change other than to suppress that error message, because t= he only difference would be that that iflib tries and fails to map the MSI-X b= ar. Regardless, that error message shouldn't be appearing at all on most em(4) devices since only 82574 supports MSI-X, and so mapping the MSI-X bar shoul= dn't even be attempted on the 82579. I don't know what to do about the queue hangs, though. Have you tried disab= ling TSO, if it is enabled? --=20 You are receiving this mail because: You are the assignee for the bug.=
