problems showing up as XFS problems on kernels after 2.6.28-git2

Quoting Dave Chinner (david at fromorbit.com):

No problem. I initally posted to LKLM, git redirected by Christoph to this
list. I'm so stupid that i didn't check the other messages from this list.
Sorry.

Yep! [cheer] i'm not alone! :-)
But why only us two ? there must be thousands of users out there using
XFS. Why did it bite us ? large filesystem together with slow hardware ?

Grwat.

Do you want me to still try it ?
I think you allready figured out where the culprit is ?!

I saw changes in the announcement of 2.6.29-rc3 and took the plunge:

over 4 hours of uptime and moderate usage, so i'm not 100% convinced but this one
looks good (so far)

Let me know if i should persue some more.

Thanks for all the help.
