From f91b392c4d20fcd2684587c0a091123c0409959c Mon Sep 17 00:00:00 2001 From: "James.Smart@Emulex.Com" Date: Fri, 28 Oct 2005 20:29:28 -0400 Subject: [SCSI] lpfc: Fix for "Unknown IOCB command Data: x0 x3 x0 x0" Fix for "Unknown IOCB command Data: x0 x3 x0 x0" messages and inability to see devices On some platforms, the host-memory based ring mgmt area was not zero. Also, driver wasn't manipulating the entire 32bits of the ring pointers.
