I found a workaround,that is, to disable attribute caching using the "noac" nfs option.
#These two worked on tiger 10.4.3 exec -c "console=ttyAM0,115200 ip=10.0.2.155:10.0.2.150:10.0.2.1:255.255.255.0:ts7250 nfsroot=10.0.2.150:/Data/nfsroot,noac" #fstab entry they have to match 10.0.2.150:/Data/nfsroot/ / nfs noac,noauto 0 0 #If use noac,sync,dirsync then gcc does not work -- http://mail.python.org/mailman/listinfo/python-list
