Hi,

In 2.6.30.x Linux kernel, the XFS_RT configuration option does not say "This 
feature is unsupported at this time..." any more. Nevertheless, when 
enabled, the feature crashes the file system in my setup. Is it expected to 
be functional?

The attached assertion log happens every time with a clean and empty file 
system.

Thanks,

Roman Kononov
