I think you've already figured out that this is an allocation issue.
However, it does seem fishy, the code is
ioc = kzalloc(sizeof(MPT_ADAPTER), GFP_KERNEL);
if (ioc == NULL) {
printk(KERN_ERR MYNAM ": ERROR - Insufficient memory to
add adapter!\n");
return -ENOMEM;
}
And MPT_ADAPTER should be just under a page which looks like a very odd
allocation to fail so early in boot. The memory subsystem should have
also printed out a trace explaining why it failed the allocation.
