knfsd oops 2.4.24

[Wakko Warner]

I was burning a cd over nfs (glad I have burnproof =) when knfsd crashed on
me.  2 kjourneld oopses followed (sorry, wasn't able to capture).

Disk is SCSI on an AHA2940UW controller.  I'm considering going to 2.6.x,
but I'm simply not convinced of 2.6's stability and I've noticed a few knfsd
problems there as well (minor problems).

I'm sure I'll beable to capture the other oopses.

The machine is an ms6163 pIII700 384mb ram (FYI, this used to be in another
machine running 2.6 and did not actually have these problems).

Any more information required will be given.

Keep me in CC
