Perhaps instead of looking at the number of bytes sent, the logic in the

??? It would be a bug for the request to be sitting on _any_ queue when
it enters xprt_transmit().

Here is the patch that I'm currently testing.

Trond,

What is the set of patches that are you testing? I'd like to give
that a spin tonight as well.

It is possible that what makes my configuration more susceptible
to the problem is the fact that the client significantly overpowers
the server: Athlon x2 4200+ with 2Gb of RAM for the client vs. PIII
1Ghz 512 MB RAM for the server. They both have gigabit ethernet
and both NICs and the switch support jumbo frames.

Regards,
florin


See
http://client.linux-nfs.org/Linux-2.6.x/2.6.21-rc7/

I'm giving the first 5 patches of that series (i.e.
linux-2.6.21-001-cleanup_unstable_write.dif to
linux-2.6.21-005-fix_nfsv4_resend.dif) an extra beating since those are
the ones that I feel should go into 2.6.21 final in order to fix the
read/write regressions that have been reported. They should be identical
to the patches that I posted on lkml in the past 3 days.

Please feel free to grab them and give them a test.

Cheers
Trond
