[SCSI] Bug 4940 Repeatable Kernel Panic on Adaptec 2015S I20 device on bootup From: "Salyzyn, Mark" <[EMAIL PROTECTED]> Prevent driver from loading if another driver (i2o) has already claimed the resources associated with the card. Discussion associated with this bug can be referenced at http://bugzilla.kernel.org/show_bug.cgi?id=4940 where it was agreed to use pci_request_regions in both the dpt_i2o and the i2o driver to prevent both drivers loading on the same adapter(s).
