Feb 23 06:04:51 zenmaster kernel:  =======================

Expected results:
System is totally stable using this driver with RHEL 4.4. 

Additional info:
The i2o_block.ko caused even worse oopses which is why I've gone to the trouble
of figuring out how to install FC6 with the dpt_i2o driver despite not having
the dpt_i2o.ko module shipped with the kernel rpms.
Comment 1 Chris Lalancette 2008-02-26 18:57:33 EST
This report targets FC6, which is now end-of-life.

Please re-test against Fedora 7 or later, and if the issue persists, open a new bug.

Thanks
