That's too bad, it would be good to see if linux clients work for 
troubleshooting.
Make sure that you have the port mapper running. /etc/init.d/portmap 
status should say
started.  If it doesn't then run /etc/init.d/portmap start and then
/sbin/chkconfig portmap on

Check this URL, too:

actually you might want to read the whole howto:

No.

Just did a quick search and it seems that you can add vers=2 as a mount 
option
for your IRIX clients to force them to use v2 NFS which doesn't have the 
problem.

That patch is for an old version of kernel and it no doubt won't apply 
to recent
versions of the kernel.  You'll probably have to try to manually 
integrate it
yourself, but...the patch (in one form or another) might already be 
integrated into
the main tree, so you might want to check kernel changelogs and such.
