System : OpenBSD 4.9
Details : OpenBSD 4.9 (GENERIC.MP) #819: Wed Mar 2 06:57:49 MST
2011
dera...@amd64.openbsd.org:/usr/src/sys/arch/amd64/compile/GENERIC.MP
Architecture: OpenBSD.amd64
Machine : amd64
>Description:
I have a Supermicro X8SIL motherboard which has 2 82574L Gigabit
ethernet controllers on it. These NICs use the em(4) driver.
Under OpenBSD 4.9 (but NOT 4.8, so this is a recent regression),
a substantial amount of network traffic will cause the console
and dmesg to report "em0 detached".
I've also seen this problem when there is relatively small
amounts of netowrk traffic, but it usually takes a day or two
of uptime before that occurs.
>How-To-Repeat:
Install OpenBSD 4.9. Attempt to transfer a 500MB file to (or
from) another host using scp(1). After about 200MB, sometimes
less, em0 will detach. This happens for both inbound and outbound
transfers.
>Fix:
Only rebooting seems to fix the problem.
