Re: XFS trouble on 2.6.0-test11

[Russell Cattelan]

Yes unfortunately this has been cropping in a few places recently,
including 2.4.

We don't have much info as to what is going wrong at the point
other than the panic is due to bad data on disk. 
Tracking down when the bad data happened it always difficult.

If anybody else hits this attach the output of xfs_check to:
http://oss.sgi.com/bugzilla/show_bug.cgi?id=296

If you're system is accessible and you would be willing to let
somebody poke around you're system with xfs_db try to find us
on irc: FreeNode #xfs
