XFS and knfsd

[Ajay Shekhawat <ajay@xxxxxxxxxxxxxxxxx>]

Are there any tricks to getting knfsd working with XFS? Our server which
serves an XFS partition gets an "oops" after about 15 hours of extremely
heavy use. I'm using the latest distro from CVS (2.4.3-XFS).  Here's the
kdb output of the oops, just in case someone has any ideas on how to
debug this:

Unable to handle kernel NULL pointer dereference at virtual address 00000000
 printing eip:
c0145933
*pde = 00000000

Any help is appreciated.
