"Unknown error 990" is a classic "wildcard" error message given by XFS.
You may want to unmount and then run xfs_repair(8) and then coordinate
with the XFS team on their mailing list for more information.

For whatever it's worth, I have a production setup using Linux kernel
2.6.11.11, DRBD 0.7.10, and XFS, and am not having any problems at all.
I am not using LVM2, though, because I was under the impression that
DRBD+XFS+LVM was not a very stable combination (see the mailing list
archives of both DRBD and XFS lists for details).

You may want to try without LVM, too, and see if you fare better.
