Kernel 2.4.3 NFS problem in combo with xfs allocsize

We just installed a new kernel 2.4.3 and experiencing problems with allocation of blocks.  With the standard debian kernel from
squeeze (2.6.32-5-amd64) we do not have any problems with the same xfs settings

xfs mount options:
 * LABEL=lisapool  /lisapool       xfs     rw,uquota,prjquota,nobarrier,allocsize=1048576k,logbsize=256k

I do a nfs 3 mount on a node and when copying small files everything is ok:
{{{
mount -o rw,vers=3
}}}

Now on the mounted directory: ls -lsrh
{{{
288K -rw-r--r-- 1 root root 288K Jun 27 13:50 bash.1
}}}

When i do a copy the file size is correct
{{{
288K -rw-r--r-- 1 root root 288K Jun 27 15:14 bash.1_cp
}}}

When the file size is bigger: ls -lsrh
{{{
1.5M -rw-r--r-- 1 root root 1.5M Jun 27 13:55 bash.groot
}}}

Now copying this big file:
{{{
1.0G -rw-r--r-- 1 root root 1.5M Jun 27 15:14 bash.groot_cp
}}}

Note the size equals the xfs allocsize option and causing problems on our quota enabled file server. When i set an allocsize of 4K
we don't see these problem. Also copying between 2 local file system is behaving as expected. Have other people noticed this problem?

Regards
