This means the filesystem has shut down, most likely, and more information about
the error is in dmesg.
Further, if the filesystem is corrupt, xfs_repair output would be interesting.
Can you provide that information?
This can probably be reproduced, but when reporting a bug it's always good to
provide
as many details as you can.
Thanks,
