0.33.1: got token w/o data!

[Bernhard Mogens Ege]

I have just upgraded from 0.28 to 0.33.1 and suddenly this message
pops up all the time:

Message from syslogd at overmind at Mon Jun 19 19:51:03 2000 ...
overmind kernel: XFS Panic: xfs_message_installattr: got token w/o data! 

And that on all xterms and in /var/log/messages

Is this a real error or can I disable it somehow. As I recall, this
was discussed for arla-0.27 which 0.28 cured (I didn't see it), but it 
has turned up again.

regards,

Bernhard Ege
