2.4.17 NFS hangup

[Burjan Gabor]

Hello,

I have a reproducable problem with 2.4.17 kernel and NFS client after
netbooting an RS/6000 (ppc architecture).

Immediately after boot:

partvis:/tmp# dd if=/dev/zero of=blah1 count=1
1+0 records in
1+0 records out
partvis:/tmp#

partvis:/tmp# dd if=/dev/zero of=blah2 count=2
2+0 records in
2+0 records out
nfs: server 157.181.150.31 not responding, still trying
nfs: server 157.181.150.31 not responding, still trying
nfs: task 913 can't get a request slot
... and so on

Relevant tcpdump output:

20:41:40.927855 heron.elte.hu.nfs > partvis.elte.hu.3648238371: reply ok 28 lookup ERROR: No such file or directory (DF)
20:41:40.928622 partvis.elte.hu.3648238372 > heron.elte.hu.nfs: 148 create [|nfs] (DF)

However, reading works without any problems.  Full tcpdump output from
