Hi, short Version: I think there might be a problem with the vte (nic) driver. I'm searching for a way to gather all the Information to get this fixed.
long Version: I've built a home router with following components. - Educake (very small X86 SBC around Arduino) [1] - USB Lan Card (axe0 nic to ISP) - USB Hard drive (nfs export) - SDHC Card (Openbsd) After some thinking (and help from various openbsd users and this list) i was able to install OpenBSD 5.9 on this device. Things are working very well. For my Connection 50mbit/down 4mbit/up this Hardware is more than enough. running Services: dhcpd nfsd/portmap ntpd sshd radicale (caldav server) ddclient (dyndns updater) unbound pf Here comes the problem. After some event i do not know vte0 is not able to receive or send any anything. Logs show nothing. Leds on the nic are still showing that there is traffic but i can't do anything on that nic. Established connections on that nic all get broken. Other parts of the system work fine. An easy way to fix this is ~ ifconfig vte0 down; ifconfig vte0 up And things are working perfectly normal again....for some time. Creating much traffic (about 40mb/s), this happens every few hours. With low traffic, it's about one or two times a week. With my findings it's probably hard to investigate/fix that Problem. I'm searching for ways to file a good bug report. Ideas ?
