While it's not the cause of your panic, you should at the very least be checking to see whether IOMalloc returned a valid pointer or 0 before you dereference "range."

But given the DAR is 0x1000, it's clear you're likely dereferencing a NULL pointer at offset 0x1000; what's at 0xB3E40? What's instruct->offset?
