So far, so good. I've ran a couple of iperf3 tests (60 seconds, trying both directions) and it doesn't crash.

Without the fixes I obtained a panic quite reliably, in less than 30 seconds.

Still trying. But the bugs you mentioned (lack of locking and deallocating, etc) seem to be consistent with the kind of failures I saw and their apparent randomness.

So, asking for spiritual counsel now. Would you use this driver  in a production environment instead of the 747 version downloaded from Emulex? I think the latter is giving slightly better performance but, anyway, I disable LRO and TSO because I see a horrible impact on NFS performance.

Cheers,





Borja.
