https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=235031 --- Comment #15 from Eugene Grosbein <eugen@freebsd.org> --- (In reply to Martin Birgmeier from comment #13) > What can you get from the ntp drift? Now we see this machine has good enough hardware timer to rule out problems linked with bad hardware timer. > Is there a way to selectively disable MSI for em0 only? No, driver does not support that. However, you have cpufreq enabled so the box may run with lower CPU frequency unless there is something like iperf running making extra load. Can you temporary configure system to run at max all the time or just unload cpufreq and repeat your tests? -- You are receiving this mail because: You are the assignee for the bug.
