[Linux-cluster] dlm spinlock BUG

[Jens Beyer]

Hi,

I am (trying) t run a GFS testcluster based on cluster-2.00.00 and 2.6.20.6/32bit
vs  cluster-2.00.00 and 2.6.20.6/64bit. 

When mounting the  shared device on both nodes I get on the 32bit node:

[82301.201322] BUG: spinlock already unlocked on CPU#2, dlm_recoverd/21239

Afterwards I have to reset the server (locked mount), while the 
second (64bit) server is still useable.

Any ideas ?
