Subject: NFS root: New error messages in latest bk

Latest bk 2.5;

Just booted with NFS root and noticed these new error messages in dmesg:

NFS: server cheating in read reply: count 4096 > recvd 1000
NFS: giant filename in readdir (len 0xcb2d2053)!

Anybody know what this means?

It means that the client can only see 1000 out of a promised 4096
bytes. Either the client or the server has a bug. A tcpdump should
sort it out.

I have almost the same, but without the "server cheating":

16:12:06 NFS: giant filename in readdir (len c8f2d9f0)!

got this by doing "find /mnt -type f | xargs cat > /dev/null".
The server is 2.4.20-ck4 (Con Kolivas patches: aavm, preempt, lolatency).

Also seen something about 7 min later (the find was still running):

16:19:22 nfs: server server1 not responding, still trying
16:19:25 nfs: server server1 OK

The "server1" (my desktop machine) was doing almost nothing at this time
and felt ok (still does).
