I'm also indicating that it happens with several drivers (bge, bce and em) on several different machines, on both pci-x and pci-e.

Sepherosa is a guy that writes drivers for BSD based operating systems. Including FreeBSD. He has a lot of knowledge in this area. http://people.freebsd.org/~sephe/ The NIC you are referring to, the one sephe recommended me, is a 82571EB. I didn't mention specific hardware, as I think it's more important to note this is an issue I'm experiencing across different sets of hardware and drivers. > > You have a problem once every 10 days, and at a specific time no > less, > this almost always means something in your environment, a cron job run > amok, a piece of hardware that resets, I dunno, but the last thing I > would > suspect given this description is the driver. This is not what I wrote. I wrote I had a problem every 1-10 days, but it would usually happen once every 3-4 days. At worst, every day in periods. It's not at any specific time. If you read my email correctly, I say it *usually* happens arround 11-13:00, but it has happened at random times too. This is my point exactly. I don't think it's the Intel-driver, I think the problem is elsewhere. I had a suspicion it had to do with the combination of nic + qlogic fc-controller, but I have no evidence of this. > > You need a good sysadmin for this debugging I would venture, not a > driver > developer. What I need is useful advice/help. I never stated I needed a driver developer. I'd like to be able to run my favorite OS on cool hardware, in the future, for a high-performing NFS-server, without problems like I've experienced the past 6months, on a production system. Please note that I'm managing a server-park almost completely based on FreeBSD, and I'm running many NFS servers on other hardware, for other services, without issues. I've seen several other FreeBSD-users having problems with this too, so I think it's of importance for the project. As I mentioned originally, I'm happy to dispose the hardware to any FreeBSD developer that might want to look further into this. Debugging it further is above my skill-set, I don't even know where to begin looking, especially since I can't produce any panics. I'm sorry to say, but your reply was %0 useful, Jack. > > Jack > - Daniel --Apple-Mail-3--565055668 content-type: application/pgp-signature; x-mac-type=70674453; name=PGP.sig content-description: This is a digitally signed message part content-disposition: inline; filename=PGP.sig content-transfer-encoding: 7bit -----BEGIN PGP SIGNATURE----- Version: GnuPG/MacGPG2 v2.0.11 (Darwin) iEYEARECAAYFAkrKO64ACgkQF4Ca8+3pySXusACfXvo7rHi8Dw/HEePHDv1wb1mS 5pEAoNNif5AYbrkgRcoJrIcYrp0p4kVW =cJSf -----END PGP SIGNATURE----- --Apple-Mail-3--565055668--
