Well all I do is for getting kdb output is to use a serial console and 
another computer - then cut and past then send  ;-).

It is very interesting that devfs is referenced - there was a LVM memory 
corruption problem and a patch for LVM/devfs - it can be found here:

- From my experience it seems that LVM 1.0.1rc4(ish) is way more robust than 
the updated LVM 1.0.1 or even CVS LVM 1.0.1 yesterday.  However, not 
everything works as expected with either. You can find a results table for a 
few tests I have conducted here: (of course YMMV)

I think you would be very interested in the discussions and activity that has 
been occuring on the linux-xfs & linux-lvm lists at the moment regarding XFS 
and LVM.  If you are seeing problems I would be very interested in finding 
out how your problems differ from mine.
