So this should really be > tested after explicitely enabling it with ifconfig +rxcsum. if ever this helps, I just came accross these messages on a (7-stable) nfs-client against my 8-stable server which passes the test : Oct 3 17:25:05 push kernel: nfs_getpages: error 1433597680 Oct 3 17:25:05 push kernel: vm_fault: pager read error, pid 26821 (cmp) Oct 3 17:28:25 push kernel: nfs_getpages: error 1435664464 Oct 3 17:28:25 push kernel: vm_fault: pager read error, pid 27017 (cp) IMHO looks like some rare nfs-miss-communication which passes silently against a 7-nfssrver but gets noticed (and corrected ..) against a 8-nfsserver /disclaimer it is late (here) and I need sleep Arno
