Hi,
I'm using an XFS filesystem over DRBD for a few weeks on this machine
and did experience an oops.

Can you run with slab debugging turned on?
Cheers,

And please upgrade to a recent kernel. I'm pretty sure drbd doesn't

I upgraded to 2.6.22.
We'll see if it improves.

I unfortunately can't play much with this machine since it is a
production server.
