I concur. We have 2 VAResearch SMP PII boxen, 2.2.9-ac4 crashed on both within
less than 30mn. I was first thinking it was AFs related but the second one is
without AFS. Nothing in the logs to report, they use DAC 960 RAIDS adapters.
Same kernel runs fine until now on rpmfind.net with high network traffic
but no SMP. The machines are stable under 2.2.5, but I was tryind to update to
get the newer nfsd .
