Mischa, 1) Consider using sendbug (1) to provide report (read section saying "The following items should be contained in every bug report")
http://www.openbsd.org/report.html 2) I suggest to provide more details about your system configuration. Most interesting is if any sysctl tuning done and if it was working system or new/fresh setup which never worked before? 3) Can it be some broken hardware? I just googled for your board / NIC and both are about 9yrs old. -- Evgeniy On Sat, Apr 2, 2016 at 7:36 PM, Mischa <[email protected]> wrote: > Hi All, > > I just tried with: OpenBSD host 5.9 GENERIC.MP#1888 amd64 > The result is still the same.
