Message-ID: <49CB78A4.3020406@krogh.cc> (raw)
Ok. I was just so happy .. (See "Status update on Sun Neptune 10Gbit
driver earlier).
But then it "blew up" again:

It is fairly hard to reproduce and pops generally up after af few days
of production. But I am willing to test patches that would help resolve
this problem as both the niu-driver and the NFSD on 2.6.29 really
outperforms the 2.6.26-rc4 + nxge driver I'm currently using.
Hardware: Sun Fire X4600, 32GB of memory
