------- Comment #2 from tytso@mit.edu 2009-01-27 07:42 -------
Looks like the cciss driver is returning an error when we try to do a write
with barriers enabled. If we get a failure return from the device driver, we
fall back to writing the commit block w/o barriers, and that is apparently
succeeding. So this looks like a cciss issue.
I've added Mike Miller, the maintainer of the cciss driver, to the cc list.
Mike, does this ring any bells; has there been any changes between 2.6.28.1 and
2.6.29-rc2-git3 that might account for this?
