https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=234766 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 the only difference would be that that iflib tries and fails to map the MSI-X bar. 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 shouldn't even be attempted on the 82579. I don't know what to do about the queue hangs, though. Have you tried disabling TSO, if it is enabled? -- You are receiving this mail because: You are the assignee for the bug.
