GFS panic in check_seg_usage

["Sridharan Ramaswamy (srramasw)" <srramasw@xxxxxxxxx>]

I'm hitting this crash while testing small file create/write/delete test with low journal size. It happened twice for me, once when I enable data journaling and the other without that.

 

This seems similar to bugzilla,

Has anyone seen this lately?

 

From /var/log/message,
