--- Comment #1 from James Smart <[email protected]> 2009-05-06 15:07:29 --- We resolved a similar panic with our 8.3.1 driver patch set. Please validate that you are indeed using vanilla 2.6.30-rc4, and that the boot strings show lpfc version 8.3.1.

--- Comment #2 from Babu Moger <[email protected]> 2009-05-06 15:40:50 --- I am sure I am using 2.6.30-rc4. You can see the messages below..
Pid: 687, comm: lpfc_worker_0 Not tainted 2.6.30-rc4 #1 PowerEdge 2900
About the version of lpfc version, looking at the sources I am seeing the following text in lpfc_version.h
#define LPFC_DRIVER_VERSION "8.3.0"
If you have any other patch on top of this please send me across. I will test and let you know.
