https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D235031 --- 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 frequen= cy 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? --=20 You are receiving this mail because: You are the assignee for the bug.=
