(it fixes the case for me) Hmm. This makes things drastically worse for me. Now it hangs during NFS startup. $ sudo service nfs start Starting NFS services: [ OK ] Starting NFS quotas: and that's all she wrote. ps axf.. 2757 pts/0 S+ 0:00 | \_ /bin/sh /sbin/service nfs start 2760 pts/0 S+ 0:00 | \_ /bin/sh /etc/init.d/nfs start 2771 pts/0 S+ 0:00 | \_ /bin/bash -c ulimit -S -c 0 >/dev/null 2>&1 ; rpc.rquotad 2772 pts/0 S+ 0:00 | \_ rpc.rquotad If I ssh into the box, and get sysrq-t output, I see.. http://people.redhat.com/davej/nfs I've kicked off a clean build that I'll leave running overnight, as I'm not 100% sure that was a clean tree I built from.
