Hi Soren,
Something is wrong in the receiving routine. I expect to narrow down the
scope of the issue.
e1000g maintains hardware statistics. You can get the receiving packet
count by running "kstat -m e1000g -i 0 1 |grep ipackets64". If the value
bumps as you ping the link partner, it's likely to indicate the hardware
receives the ping packets. Otherwise the interface just doesn't receive
anything. If the value does bump, could you run wireshark or snoop on
the problematic machine to see if the outputs contain any receiving packets?
Regards,
Miles

I've been experiencing some strange behavior with a new SuperMicro X7SPA-H
motherboard. I've been able to install Opensolaris and upgrade to b133, but my
network interface keeps dropping out. Just now, with my uptime at 15 hours, the
solaris box stopped responding to pings. ifconfig shows a normally-configured
e1000g0 interface, and there's nothing out of the ordinary in
/var/adm/messages, but that interface can't be pinged.
Except ... not really. According to Wireshark (running on another machine) my Solaris box is
sending ping packets to other machines on the network and getting responses, but it's not receiving
those responses. I can see ping packets leaving e1000g0 and ping replies being sent back, but the
Solaris box doesn't see those replies and reports "no answer". My Solaris box is also
sending out a bunch of ARP "who has" requests and my router is responding with a valid
answer, but e1000g0 doesn't seem to be seeing that response either and keeps repeating the request.
Anyone seeing something similar? Anyone have any idea what's going wrong, or
how I could narrow down the problem space the next time this happens?
Opensolaris has been absolutely stable for me for the past year and a half, but
this new motherboard seems like trouble.
