Hi,
I have done a Robustness Regression tests campaign using RHEL5.1 Public
Gold (2.6.18-53.el5)
in front of a Fedora Core with linux-2.6.24-rc2-CITI_NFS4_ALL-1
including kerberos on X86_64 Intel machines.
Results are available at : http://nfsv4.bullopensource.org/
Best regards

hi,
Running as client RHEL5.1 Public Gold on a X86_64 bi-ways and
as server 2.6.24-rc2-CITI_NFS4_ALL-1 on a X86_64 bi-ways,
I get the following Oops on the server when on the client I run
in a infinite loop iozone with -U option:

./iozone -+q 30 -ace -r 64 -i 0 -i 1 -i 2 -f /mnt/nosec/nfs4_gb -U

This is the BUG_ON() in svc_xprt_enqueue(), here:
process:
if (!list_empty(&pool->sp_threads)) {
rqstp = list_entry(pool->sp_threads.next,
struct svc_rqst,
rq_list);
dprintk("svc: transport %p served by daemon %p\n",
xprt, rqstp);
svc_thread_dequeue(pool, rqstp);
if (rqstp->rq_xprt)
printk(KERN_ERR
"svc_xprt_enqueue: server %p, rq_xprt=%p!\n",
rqstp, rqstp->rq_xprt);
rqstp->rq_xprt = xprt;
svc_xprt_get(xprt);
rqstp->rq_reserved = serv->sv_max_mesg;
atomic_add(rqstp->rq_reserved, &xprt->xpt_reserved);
BUG_ON(xprt->xpt_pool != pool);
wake_up(&rqstp->rq_wait);
} else {
(Tom, you can get that particular version from my git tree if you want to take
a look--there's a tag for 2.6.24-rc2-CITI_NFS4_ALL-1. It appears to be a
version of the transport switch from mid-october?)

Bruce:
I've looked at this last week, btw, I requested a login on Bugzila to
comment directly, but haven't received an account yet.
I was unable to reproduce this in my code base, however, I haven't yet tried
it with your tree, so I don't have a definitive negative test.
I'll clone your tree and see if I can reproduce this.

OK, thanks! (Note you shouldn't literally need to clone if you already
have a git repo; just
git add bfields git://linux-nfs.org/~bfields/linux.git
git fetch --tags bfields
git checkout 2.6.24-rc2-CITI_NFS4_ALL-1
That'll be a lot faster!)
