--- Comment #25 from Peter Eriksson <peter.x.eriks...@liu.se> --- > Do you have any scripts that reconfigure the interface (ifconfig ixl0 down > up/mtu/tso) while it receives/transmits traffic? Hmm... Aha! Bingo! When testing on the production servers (that always receive SMB/NFS/SSH traffic) I just did an "ifconfig lagg0 tso" to enable it and then started my iperf3 testing (and some off and on to get test data). I can now reliably reproduce this if I start an "iperf3" test session between two servers and while it is running disable / enable tso "on the fly". I can now provoke the "hang" on: FreeBSD 11.2-RELEASE-p6 with ixl driver 1.9.9-k and firmware 5.60 FreeBSD 11.2-RELEASE-p6 with ixl driver 1.10.4 and firmware 6.80 I've not (so far) been able to provoke it to occur on: FreeBSD 12.0-RELEASE-p0 with ixl driver 2.1.0-k and firmware 6.80 Sometimes it self-heals after a while, but most often I have to do an "ifconfig lagg0 down ; ifconfig lagg0 up" to get it to recover. -- You are receiving this mail because: You are on the CC list for the bug. _______________________________________________ freebsd-net@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-net To unsubscribe, send any mail to "freebsd-net-unsubscr...@freebsd.org"
