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. -- This message posted from opensolaris.org
