[PVFS2-users] Fedora Core 2 (AMD64) w/ v0.6.4 kernel modules

Hi..

/*
Base OS: Fedora Core 2 for x86_64/AMD64, updated fully.
Kernel: 2.6.8-1.521smp
PVFS2 release: 0.6.4
*/

I'm having some problems getting pvfs2-client and the mounting of file 
systems to work reliabily.  I've been reading the mailing list, but 
haven't seen these exact errors.  The pvfs2-ping, pvfs2-ls, pvfs2-cp 
utilities all work 100%.  This is my first PVFS2 install.. so I will 
appologize for all of my mistakes now :).  I've tried re-compiling the 
source code twice in /usr/src but have receive the errors both times. 
These kernel errors occur if I have one or more IO servers.

Does anyone have any suggestions as to what is going on below?

Has anyone successfully gotten Fedora Core 2 for AMD64 to work w/ PVFS2??

Thanks!

-Mike
